^^ Nice....I'll give it a go ;)

I too have been using RE for a few years now.

Cool, blackavenger, let me know how you get on.

Something I forgot to mention is that the interface includes a musical visualisation called a chromagram. I've found it quite useful for visualising chord structures, melodies and key changes, and I think it's pretty unique in the DJ software world; I haven't seen any other tools that have something similar.

You can see an example screenshot on the page linked in the OP.

This is amazing, you need to try and link with someone with capital & or connections and get it in the right hands im sure you can make a buck selling the technology. I can't imagine someone at digidesign or ableton not being interested in this. Good luck kid, congrats!

If its any good why not sell it to serato, make it a part of building overviews :D
I jumped ship from RE to MIK about a year ago, mainly for convenience.
Now, a built in key detector in SSL/Itch sure would be nice.

Will be trying KeyFinder myself over the next few weeks, thanks!!

One could only wish......

@Jordan Laws: thanks man. There's actually very little new science in there; I figured out how to build most of it just by reading a bundle of academic papers.


I agree, though all the algorithms available have patchy accuracy... is it better to have a wrong key estimate than none at all? I think it probably is - at least it's a starting point - but I can see why a lot of DJs would disagree.

And while I'm very happy running this as an open source project, Serato are entirely welcome to hire me to integrate it into the overview builder =)

impressive - thanks for the effort!

I'll give you some feedback, thanks for all the effort and making it open source first and formost.

Please understand I'm just giving feedback here not complaining :)

1. Would like to have the option to cancel operations one I start. I had to kill the program to stop a miss-fire on my part

2. Custom key codes is nice. Maybe adding a Camelot wheel preset in that drop down box. (www.djwhitehawk.com) Which is the system that a lot of people use. Including myself

3. Would like to see the program be able to write to the 'initial key' tag in a music file. Serato reads this tag.

I tested 10 for 10 in the key of Bm (Camelot 10A) against Mixed in Key (community.mixedinkey.com) In styles ranging from Ludacris to Lemmy :)

@DJitalSneaky.


It's not obvious, but you can safely cancel a batch job just by closing the batch window; any other open windows will stay operable. Not ideal, I know. I did intend to add a cancel button but it clearly got lost at some point! I'll stick it on my todo list.


I use the Camelot codes myself. However, they're now the intellectual property of Mixed In Key, so I can't include them in the software without a license.


I looked at that. According to the spec (www.id3.org), that field can only hold 3 characters, and I wanted to store the key and a code, hence the Grouping tag. But I will go back and add the option to write to Initial Key; it'll just cut off anything longer than thi.


Very good to know! =)
And thanks, I appreciate the constructive feedback.

Really did not know that about the camelot codes, thaks for the info :)

Pretty fresh stuff. You need capital and make this into a reality... You are about to give MIK a run for their money.

@DJitalSneaky

Just uploaded a new version with a cancel button, and some support for the Initial Key tag.

I couldn't test the tag stuff much. I almost exclusively use ALAC files, which don't have that tag according to the spec (I think Serato writes to its database rather than the file itself in such cases). But it works well on MP3s. Let me know if you have any trouble.

Awesome program, thnx alot. Too bad that you cant use the same keys as they use in mixed in key

@Dj_Roger

Thanks man. You can of course type whatever you want in the Custom Key Codes preferences pane.

that's nice, but takes time if you analyse a lot of songs ;-)
anyway..... awesome program.

I think maybe you misunderstand.
Go Preferences > Tags. You'll see 20-odd boxes where you can type custom codes for the keys. Then set Write Tag Format to Custom Codes or Both.
That way, you can set what's written to your files to something other than my "Abm" style tagging.

ohh ok i´ll do that :-)

Sorry my Music Theory is a little rusty, are these the correct Camelot codes?

dl.dropbox.com according to this www.harmonic-mixing.com

@Konix
That's exactly right.

@deejaysomething

Wow, im so impressed with this program. analyzing is accurate and fast!
Good job!!

@Djstylez23

Thanks a lot =)

Thnx alot Konix

And it reads mp4's too!!!

This prog is full of win

It's working really well, thanks

speaking of key detection, can anybody that mixes top40 link me to a mix fully done harmonically? I want to hear the difference from just a random mix to see if getting on the key detection train is worth it

downloading now... after reading this it definitely seems like you might want to think of packing this up and selling it. can't wait to try it!

im gonna make a mix later tonight and post it with a few tracks analyzed with this program. so far so good in my opinion.

Damn...for some reason I can't install this program on my Mac...it says "KeyFinder.dmg not recognized" (cannot mound the disk)

Any ideas??

cannot mount**

+1

im gonna make a mix later tonight and post it with a few tracks analyzed with this program. so far so good in my opinion.

I've got the same problem, running OSX 10.5.8

@CrowdCTRL, WarpNote

Sorry gents, try this zip file instead. Might be a 10.5/10.6 thing.

ibrahimshaath.co.uk

Thanks, for some reason I'm not able to run it.
After starting the application I get the infamous:
"The application KeyFinder quit unexpectedly."

Ultra helpful error message =(
Can you bounce me the crash report, maybe? If you send it to the email on the KF page I should be able to check it out at the weekend.

Of course, it might still be a 10.5 thing. Unfortunately I don't have anything other than Snow Leopard to test on.

Downloaded will give it a try :-)

Hehe, sorry about that Ibrahim, Ive sent a crash report.
Seems to be an issue with libav...

@WarpNote I was getting at Apple, not you =)
I'll look it over.

Sorry deejaysomething, No go for me either...
"unable to unarchive keyfinder zip into downloads. (error 1, operation not permitted)"
10.5.8 + i am an idiot.
Let me know if i can help in any way.

@djbanno
No idea, sorry. Maybe a corruption of your downloads? My web host is quite crap.

But as WarpNote has discovered, it's probable that Leopard needs a different version of one of the core libraries anyway, so it might not work even if you had an uncorrupted file.

Does anyone have this working on 10.5?

Haven't gotten a chance yet to create a mix yet but I did analyze the top 10 beatport songs on both Mixedinkey 5 & Keyfinder to compare which one analyzes better.

On Beatport all the right keys are inputed so I compared them to both programs to see which one was more accurate.

img510.imageshack.us

Mixedinkey got 6 right
Keyfinder got 4 right.

Actually I contacted Beatport when they introduced that feature: they use a piece of software to do their keys, so there's no guarantee they're correct. They wouldn't tell me which software.

It wouldn't surprise me if MIK got better accuracy than KF in some circumstances, though. =)

oh okay then my bad on that one, actually thought the artist were the ones that inputed the keys... :x

Same here...

@CrowdCTRL
Are you also running 10.5?
Bit difficult for me to recreate any of this; I just don't have enough computers =)

Doing a quick read around, it seems like this may be a problem with my upload client. Won't be able to get home and test a different one for a day or so.

CrowdCTRL, djbanno, can you try another way of unzipping please?
Open a Terminal (Applications > Utilities > Terminal), type unzip, then a space, then drag the zip file to the terminal window. Then press return, to execute the command. It should unzip in your home folder, in theory.

Tried ^^ and got two dif results from both times i downloaded the zip (neither worked).
I think you might be right with the upload client call, my downloads say the file should be 20.8 Mb but i keep getting dumped early (maybe 10Mb or so?).
I have a reliable connection my end (reg download 100 + Mb at a time).
I am downloading tracks from beatport as we speak...
I can PM you screendumps of the terminal window, etc when i get home after work tomorrow if you like.
Sorry to be a pain...

No pain, man, it's all good. Please PM me the screendumps for reference.

That does suggest my FTP client sucks, yeah. I'll try another, prob tomorrow evening.

Cheers :)

Uploaded with another client. Could you guys try again?

I think it's unlikely to work under 10.5 in any case, but one problem at a time =)

There's a Windows version up now. Probably a bit unstable, and only tested on XP so far. But I had to start somewhere =)

i can help test for windows (i run win7 x64). if you need hosting for your files, try www.multiupload.com

@babooza69
Thanks a lot. I'm fine for hosting, the initial Windows version is up on my website, but any testing effort would be appreciated.

Drop me an email if you want to discuss.

i couldn't open the program, says i'm missing MSVCR100.dll

You're missing run-times for Microsoft Visual C++ 2010.
You should be able to download that from Windows update or Microsoft's website -- or a redist should be packaged a long with a lot of software.

Seems folks have been getting some good results from this with no serious issues... running my first batch now. Thanks for putting this out there, and for free. The detailed analysis window is kind of hard to read, but I can see that being a very useful tool.

ok, the batch finished running and I think I've hit a snag. KeyFinder detected keys for all the songs, but it doesn't seem to have written anything to the id3 tags. Is there a step I'm missing here?

Yup. Select all and then hit Cmd+T (or right click for other options).

I don't like software that automatically screws with my record collection =)

That did it lol. So it doesn't actually alter the file in any way until you tell it to? I kind of like that. Awesome piece of software here....

Well, I am happy with it, it's only refused to Key a few tracks.....I prefer it to MIK & RE now.

Damn still a no go for me even after trying the latest version u uploaded. Must be cause Im on 10.5.8 i guess??

been asking for ages, but they are too interested in making programs for noobs with bells whistles & sync buttons!

ialso cant get this to install at all as soon as i open the zip file & click on the exe i get an error message tried to download it twice too.


Any idea? Im using windows

msvcr100.dll is mising is the message i'm getting

First off, THANKS for such a program to use and try and for FREE! 2nd, While i was reading this whole thread. I was thinking to myself, why won't you have a different version, released under a different name, and release it as a PATCH into SSL. I know it goes against their terms/license? but, really,,, Most of us need this INTEGRATED into SSL forreals. Whether it's in Prepare mode (disconnected hardware)-(more favored) or with the hardware connected (drag and drop detection). I know it sounds more going warez style but I always 'dream' of the day that some brillant code chugger comes out a patch for SSL to patch and enable a piece of software like this to run different PLUGIN or to be as a feature, INTEGRATED right into the SSL GUI. Cause deejays been whining on these forums for 'maybe' a couple of years for something like this. I come from a MIS background and now pretty weak at coding in Visual Studio and other misc. languages, but I know SSL or ITCH is coded at machine code level(majority?). I'm just throwing a different idea for you to approach something for SSL or probably ITCH to reverse engineer and to be able to add a feature to Serato's SSL software, it's a kinda sorta thing I may implying like how MixEmergency has opened a different door for Video-SL.

Got the download to work sweet, unzipped fine and then same^^ for me.
I gotta say i hope you getting PM's from Serato for this project cause you deserve some major support.

usefull and straight to my lives with my partner. thank you! this should be include as a part of "analize" in Ssl:)

I couldnt agree more key detection should be intergrated

How do you make the keys come out in the 6a 6b etc format i have been tring to find a conversion way on the net ? so like from the way this progrme does the keys

@matty k, i think Konix's post is what you are needing ^^

Cheers nice one :-)

would be nice if you can make it run without it...don't want to install a bunch of random stuff on my dj laptop if you know what i mean

Where is everyone saving these keys to? To be able to see them in serato ? cheers

Matt

I know exactly what you mean. Unfortunately, I'm no kind of Windows dev. I would guess that libraries like that are necessary (especially using a cross platform framework), it's just with most software packages they would be installed to windows/system32 without you knowing. =)

the key file obviously???

Ok so I downloaded the last one, now I'm getting this message come up!

libgcc_s_dw2-1.dll as missing instead!

Any ideas? I really wanna check this shit out!

Right i have tried all the drop down boxes but still can see them in serato even afer rescannign id3 tags i open key box and there is nothing in there ?

@Nicky Blunt

A user on DJTT found these errors and fixes:

mingw10.dll is missing: extract www.dll-files.com into the keyfinder folder

libgcc_s_dw2-1.dll is missing: put pt.sourceforge.jp in the KeyFinder folder

I'll try and take care of these dependencies in the next version I upload but I'm short on time at present.

I think u have to activate something in the actual program. But I cant even get it to work at the moment so i really cant help much. Sorry I thought you were asking where to place the info. my bad.

no problem thank you so much for your assistance!

I'll try to get it to work. But please make sure to let me know when its up & running with the updates! Really appreciate it!

Ah, sorry, I fucked up the copy and paste. That bodes well, huh.

Those URLs again:
www.dll-files.com
pt.sourceforge.jp

Yay its working worked out i need to once i had done the group of files i wanted to analyze then i highlighted all the tracks and went write to tag thats what i was forgeting lol

man I really wanna get this program to work! Im struggling with these files I need to download.

Wish i wasnt a computer retard!

@ deejaysomething

Hi really like this programe but it doesnt seem to want to write to the id3 tags with mp4 files it does the analyzing but wont write to the mp4 just says 0 tag writen ?

Is there a prob or am i doing something wrong ?

cheers matt

I've been putting mine in "Grouping", simply because that's where I have been putting them in RE for the past 5 years. I did it for consistency!

As I undertstand it (and certainly according to the tag library KF uses), MP4 files use iTunes metadata structures. not ID3 tags. Only ID3v2 supports the Key field, that's what "limited support" means in that dropdown. So, in short, use one of the other fields for MP4 files =)

Very nice Ibrahim!
I got a Win7, 8 core laptop, SSD & 16Gb Ram, in addition to my mpb 10.5.8.
Will put it through some tests and let you know how it performs.

Ah ok cheers nice one :-)

Thats what i think i will do with the mp4s :-)

Hey, deejaysomething!

First off, thanks for this super lightweight package. After having to use RE for years, I got pretty tired at how slow and buggy it was. I was about to bite the bullet and buy MIK until I found this post yesterday and tried out your app. It is great! I do have a small issue however. When I'm detecting/writing tags to small groups of files, it works quickly and easily, but when I try to detect keys for thousands of files at a time (I tried both 5000, and 10,000 at a time) it seems to crash about a quarter to half of the way through. Hope this gets fixed!

Specs:
MBP 2.3 GHz i5 early 2011
4 GB RAM
SSD+HDD
Snow Leopard 10.6.8

Let me know if you need help troubleshooting! :)

@Weststar
Thank you, I'm very glad you're finding it useful. However, I can't immediately explain the problem as I've run batches of over six thousand files through it without any trouble.

Could you email me a copy of the KF log? Should be at ~/Library/Logs/KeyFinder.log if I recall correctly (I'm not in front of a machine). Also, if you can remember, you could highlight the time of a crash. That should give us a place to start looking; might be a file it disagreed with.

Seems to be a great little helper. :-) Would it be possible to add m3u or iTunes playlist import? That really would be awful!

@deejaysomething. GREAT APP!!! i have done my whole library (minus mp4's since i love using the key tag and already use comments and grouping for other things). Thank you!

What i have found that causes the crash are files that have a short playing length... when i took these out (short 10 second samples), everything was great... people can test it themselves with some of their scratch samples, or sp6 airhorns and other stuff and see what the length is that crashes. After that just sort by the length column and do the files from there.

Once again, thank you! I setup my custom codes nicely and its AWESOME

@SiRocket

I appreciate the props, thanks. I'm really pleased that you guys are finding it useful.

Your bug diagnosis is probably bang on; I can think of a couple of reasons that might be happening. Doesn't happen on my samples, which tend to be WAVs, so maybe it's the way KF handles short durations with a particular decoder.

Can you maybe send me a file that always causes a crash? With that, it should be a simple matter to fix, he said, foolishly.

And, out of interest, where would you store key in an mp4 if you had a wider choice (say, of all the iTunes-accessible fields)?

@Nyx

Actually, yeah, it was a nice-to-have feature that I originally planned, and then forgot about! As I recall m3us are pretty simple, and iTunes playlists can be exported as XML, right? Should be straightforward to grab a bunch of file paths out of those formats.

I'll give it some thought. Cheers.

@deejay - ill pm you a link to a file that crashes early this coming week (out of office today).

and regarding the video storage i wouldn't mind the label or remixer tag area (if they are available in mp4). I don't use either of them, i already started using composer tag for a few codes.

First off, great program. Thank you so much for handing it out for nothing. All your hard work is greatly appreciated. It seems to me to be way more intuitive the RE.

I too am having the same problem as Weststar. I get through about 3500 files and it quits. I have been analyzing smaller batches, to get around it.

Other than that, it works great.

Oh, and specs:

MBP 2.53 i5
4GB ram
Mac OS X 10.6.8

@deejay

Great program! Thank you for the hard work you put into this and willing to share with all of us.

@skitz...have you tried to organize by file length??... do all the files that are over 1minute long... see if you still have issues.

ill give it a shot. Thank you

Ok,I figured out what files were crashing the program. I narrowed it down by analyzing my music in alphabetical order. I started with all the "A" folders then all the "B." eventually i found that i have two old itunes files. I am talking about the 128 kbps aac files with an extension .m4u. those files crash it every time.

So I analyzed my library without those files (that i need to get rid of anyway) and it worked great.

Thank you again.

@Skitz

Nice catch. Were they DRM'd by any chance?
And can you email me one of them, maybe? Be very useful to see the nature of the failure.

Cheers

Sent the email

@Skitz
Confirmed that the file crashing your installation was DRM-protected. KeyFinder can't deal with that kinda thing; I might be able to make it deal with them a bit more gracefully though.

Glad you got your batches working.

Upon opening the program I am getting the error message:

"You can't open the application KeyFinder because it is not supported on this type of Mac."

I am on a 2006 MacBook Pro - Intel Core Duo running Snow Leopard 10.6.8

@Solidsnake

I think that will be the same problem as the guys running 10.5: probably a CPU architecture thing. It seems to run fine on C2Ds (on 10.6 and later), but I don't think older processors or versions like the 64-bit-only architecture.

Sorry. My expertise in this particular area is limited. It should be possible to make a version of KeyFinder that supports i386 as well as x86_64 (requires dual-architecture versions of the libraries) but I haven't got it working yet. If there are any Mac deployment experts lurking out there (or anyone who knows one), please speak up!
Probably the best I could do is switch the entire app and its libraries to 32-bit, which might slow it down for everyone else, so I don't really want to go there.

That's what I had figured, this is cool for me to look at as I'm a Computer major too and I'm about to start programming courses next semester...

Aha... Well you should feel free to download the source code, and take any C++ modules they offer you ;o)

Best of luck with the course, man. I'm supposed to get the final grade from mine in a couple of weeks...

strange, I'm on a 2006 macbook with a core 2 duo running osx 10.6.4 and keyfinder worked fine for me... wonder what the difference is

loving this so far. i think i'm done with MIK. it's silly that it's so expensive to upgrade a software i bought two months ago. and even though i decided not to upgrade i've gotta deal with a stupid pop up asking me to upgrade every time i open the program. what if your car wouldn't start after the next year's model came out (a reality for most Kia owners)?

anyway.. wondering if you could make the "Write Tags" function a button rather than a menu option. it would just be a little cleaner in my opinion. had trouble finding this the first couple times i used the program and found it quite frustrating until i did a little reading and figured it out. just a thought.

thanks man!!!

+1

That would be very easy, though I'm not sure where it would fit, real-estate wise.

I guess I'd like to somehow make it clear that such a button would write to ALL the files that had been analysed, and then the other function could be left in there if you just want to write to a subset.

Sound sensible?

+1

Has anybody got this working on a Vista machine??

its mac only for now i believe.

there's a windows binary but it's not fully tested on all iterations of windows

It's because you have a Core 2 Duo and mine just Core Duo, your laptop has 64-bit architecture while mine sits at 32-bit (also reason why I cannot upgrade to Lion, but that looks to be more of a blessing so far minus missing out on iCloud)

Well I got it working on a Vista machine but if I try to add more then 1 track it crashes on me?? Any ideas? An error message pops up and just says something has made the program stop work blah, blah, windows will check for a fix.

Yeah, that's been reported before but I can't recreate it, sorry. I need access to some different Windows versions. Hopefully there'll be a fix at some point soon; it's probably a pretty straightforward bug.

Cool, Thanks for the quick response :-)
Looking forward to a working copy.

I just downloaded it for OSX and it will not unzip on the latest Snow Leopard

still no joi with this on windows. guess i will use rapid evolution

Time for a quick Sunday morning release... a new version is up at ibrahimshaath.co.uk, which should take care of:

* SiRocket's short file crash; increased stability for large batches
* Skitz' crash: it shouldn't break if it comes up against a DRM'd or badly corrupted file.
* M3U playlist support
* _some_ Windows dependency issues

Next priorities:
* Add option to write to tags automatically for Sureshot et al.
* Get a 32-bit Mac build working
* Hopefully fix Windows
* iTunes XML support

~ Downloaded this last week and I love it...Thank U.

The only problem I had with it is that it won't read or analyze tracks that have a different character like "Beyoncé", "Keshia Chanté", "Sigur Rós" or "Blade (200° C Club Remix)". Things like that. :)

@DJ506
Hey, glad you like it.
Yeah, I came across this problem with non-ASCII characters in filenames during the original build but haven't found time to research it. It's already on the to-do list!

~ Awesome! Thanks again. :)

Hey deejaysomething;

I've downloaded the windows version and unzipped it .. i try to run the .exe and i get this error

"this application has failed to start because MSVCR100.dll was not found. Re-installing the application may fix this problem"

i've downloaded it a couple of times .. and still get this error ..

i'm using windows vista 32 bit .. any thoughts ??

Hey dirrtyharri,

This is a known dependency; please look higher up this thread, or at the FAQ: github.com.

Cheers

ok great .. i'll give it a shot .. thanks !

Another thing you can try is downloading the missing DLL file here:

www.dll-files.com

and then placing it where the KeyFinder.exe is at.....

When you do download the dll put it in the folder with the app. That's what I had to do but still it would crash on me if I loaded more then one file at a time. If you do get it to work please let me know though, thanks.

i've got the missing dll .. it's working now .. but i'm having the same issue .. it will crash if i load more than 1 track into it .. also it's not writing the key to the file..

got the program to load, it appears to be working fine. Ive not tested it fully. But I'm totally stoked. It looks great. Thanks for all your hard work. You are a legend!

his development pace is faster than serato's, thats a big plus these days :D

fixed :P

works good!!!! i like the "sirocket add on" :p

Cheers gents =)

I can't recreate the crash on adding a second file; it'll probably be something dead simple (that whole section of the code is only about thirty lines IIRC).

Can someone who gets that crash email me some details, maybe a crash report or whatever Windows spits out?

In regards to using the Camelot system, what are you guys putting in the field for Gb & Gb minor?

Does Camelot simply not use flats for G maj/min, or what?

Gb = 2B
Gbm = 11A

G-Flat minor (Gbm) is unusual and not used often, so it's usually replaced with F-Sharp minor (11A). At least that's what I can gather.

Ok I was thinking just to use the F#'s but I just wanted to be sure. Thanks

Gb and F# are the same note

there is a theoretical difference, but the difference is musical semantics for lack of a better term

Another minor release for you at ibrahimshaath.co.uk, including:

* Option to write to tags automatically (check the box in Preferences>Tags)
* Support for UTF-8 filenames (see DJ506's messages above)
* Bug fixes including some M3U problems
* I stripped out all the crap algorithms now that my project's been marked!

Next priorities:
* Get a 32-bit Mac build working
* One day, fix Windows builds
* iTunes XML support (meh)

Enjoy!

nice on the auto tags!!!

GREAT app! Can I make a small feature request to increase the functionality even more? Can you have a toggle for 'skip if tag already exists'? I think I can speak for many of us when I say that some of our tracks do have key info in the key field, and it would be nice to be able to drag/drop an entire folder and have it ignore the ones that have keys.

Yeah, I'll take a look at that. It's on the list. =)

Thanks!

This might sound dumb but im not very familiar with all the options you have in your tool, i currently use mixed in key which offers very little customization and is very user friendly. Would i get the best results by leaving all of the default options?

I tested with 2 tracks and with your tool they came up as Cm and with MIK came up as Fm. I left everything default with your tool.

If you don't know what an option does, leave it alone. Some will have a huge effect on accuracy, some less so.

On some tracks, MIK will be right and KF wrong, some tracks vice versa. On many, the two systems will agree. But detecting key is not an exact science.

Cm and Fm are exactly a fifth apart and very easily mistaken, even by a human in some cases. They're highly compatible; note how close they are on the camelot wheel.

Good stuff, thanks for the info.

np =)

A new release is available at ibrahimshaath.co.uk, including:

* Multicore support! Batch jobs should now be much faster, though your CPU fan may get a little noisy. Mine did. =)
* Fix for handling of Comment tags on FLAC files (not so relevant for Serato, obviously).

Next priorities:
* Get a 32-bit Mac build working
* One day, fix the Windows build

As ever, shout if you have any issues. And if any interested devs are lurking, I could use some help with the Windows build.

Wooo....hooooo!

8 threads of KeyFinder magic is now the order of the day. Thanks soooo much, Ibrahim!!

You're very welcome =)

Anyone getting a group of failures at the beginning of a batch job, I've just uploaded a version with a quick hack that should fix that.

i'll cop it tonight sir :)

any devs for windows, I know johnny M knows his way round a windws machne pretty well but idk if he can write code.

Im a windows dev been meaning to take a crack at it.

please do ben, this would be totally appreciated, As im having no luck installing it on any of the laptops i have.

tehBEN, that is excellent news. You know where to find the source, but shout if you need any help getting libraries etc.

Can Key-Finder also find my house keys for me? Have been looking for them everywhere...but no luck :-(

yes all kind of music including House

^ LOL

^^ FPMSL ;-)

lol at the house question

Guys, so this pretty much eliminates purchasing MIK?

I like it better, so yeah!

waiting for window fixes!! hehe

+1 i deffo want to get it going or imma have to buy MIK & I really dont want to

windows.... #crickets

Hey love the program, however it crashes every time I try an mp4 file, any idea why? Using macbook Pro.

FYI... He is working on the issue as we speak... sit back and hold tight :)

(I have same issue as you)

MP4 Issue Resolved!

Thanks deejaysomething!

DJPNUT heralds my coming. Sure enough, v1.1.7 is now available for Mac at ibrahimshaath.co.uk

This includes various bug fixes (including for mp4 video decoding, sorry about that one) and newer, hopefully stabler versions of various libraries.

So, in other news, I've been looking at the 32-bit Mac thing with the aid of some very helpful forum members but, in short, it's a real pain. So I wouldn't count on it happening soon. It's still on the list though. I am making some progress on Windows, having finally landed a Win7 license.

Happy new year everyone.

^^ score!

I just wanted to give a big THANK YOU as I found this tool to be super useful and have keyed all of my dance music!

shouts to deejay for the hard work on this!

FYI, Kilmore from Incubus is using your software now, we had a session the other day at his pad and i showed him your software and he had to have it :)

Good for you....way to pay it forward, SiRocket :)

Absolutely. Cheers SiRocket. I appreciate the promotion, mate. =)

For those who are interested in harmonic mixing, DJTT have posted their annual comparison of key detection software here: www.djtechtools.com

They didn't include KeyFinder, but whatever. =)

^ Sorry, not annual, obviously. In fact it's been over two years. Oh, for an edit function.

Did you submit it to them? Seeing as how Traktor bias they are, and the fact that they probably never visit this site, they may not even know KeyFinder exists.

Personally, of all the Key Detection software I've used thus far, KeyFinder is my favorite!! So thank you again, Ibrahim ;)

+100000

Thank you fellas. Here's my own comparison =)
ibrahimshaath.co.uk

Nope, I didn't submit it, it didn't occur to me.
In a lot of ways (e.g. multicore stability - which I have plans for - and, as ever, Windows support) KF's still very immature; I only wrote it six months ago and it has a developer population of 1. That's pretty small for a project with apparently a few hundred users. But next time there's a high profile comparison, hopefully it'll be a competitor.

And what do you know, it's a new version.

New version 1.1.8 is available at ibrahimshaath.co.uk, featuring:
* more stable multicore performance
* the option to disable parallel processing, to reduce CPU load
* support for iTunes XML libraries and playlists
* boring bug fixes.

As always, shout if you have any question, problems, feature requests.
This update is Mac only at present, apologies to Windows heads.

First column correct key, second compatible?

Yup. Really should label the columns individually.

The compatibility score is the MIREX one; their system (if I recall correctly) is that you get 1 point for an exact match, 0.5 for a fifth/fourth out (C>F), 0.3 for a relative key (C>Am) and 0.2 for a parallel key (C>Cm). Seems a pretty fair system.

Haven't tried the latest builds, same issue for 10.5.8 ?
Been holding off as I'm planning a new mac later this year...
So will probably switch from MIK then.

Yeah, sorry WarpNote. Trying to get a 32-bit Mac build working has been nearly as painful as the Windows build, and that's saying something. I'm sure it's possible, but I just can't prioritise it. =(

No worries, I will have to upgrade that old mac anyway, just asking.
Stay focused on making the current platform good for the newer OS, cant wait to switch :D

Is there a way to just import songs that don't have anything written in the key or group tags? Sometimes my library fills up and I forget to key the songs individually, so going to every song locations' folder and dragging to KeyFinder takes painstakingly long.

Hey Weststar,
Not at present, but it sounds to me like you're describing two problems?

Firstly, yes, KF will analyse all the songs dragged to it, although I'm working on a feature request to skip over songs where tags already exist. Might be in the next release, might not.

Secondly, going to all your song folders and dragging them in... Well that shouldn't be necessary. KF will accept playlists in M3U or iTunes XML formats, and it will also recurse through any folders you give it. So if you are paranoid about missing a track, then (assuming your music is well organised) you can just drag in your top level Music folder and wait for the import to finish.

Hope that helps.

That would help tremendously!



This is a good feature, but somewhat leads into a problem that the "skip over songs where tags already exist" will ultimately fix.

See, when I import my entire iTunes library and detect those keys, it detects keys for songs that have already been analyzed which takes an unnecessary amount of time. I should have been a bit more specific in my previous post; my problem is that I only want to detect keys for songs that haven't been scanned/don't have keys written in the key/group fields. Right now, it seems the only way to do this is to import the albums/songs individually, and when I happen to let a lot of new tracks build up in my library, importing these individual tracks takes quite a long time.

Does that make sense?

Thanks for the quick response! :D

Ah, I see. So you were only describing one problem, in fact! =)

Well, I'm on it. Check the next couple releases, I'm sure it'll be in soon.

any news on the windows releases????

@Nicky Blunt

Some. Nothing much to shout about. Main problem right now is, I got a new build of the decoding library, but it crashes on various file types, and it shouldn't.

On the plus side, I can recreate the crashing-on-adding-two-files bug.

Slow progress, basically. What was the problem you were having, again?

i will pm you if thats ok to keep from cluttering your thread. :)

Good evening ladies and gentlemen,
I'm proud to release KeyFinder v1.1.9, which you can get here: ibrahimshaath.co.uk

Features include:
* GUI enhancements including live tag updating and simpler Preferences window
* option to write to multiple tags
* option to skip files where tags already populated
* parallel (faster) metadata reading for big batch jobs
* use of keycodes in detailed analysis window
* support for Japanese charsets (on the Mac, at least)
* CLI (sort of) and drop-to-dock-icon (Mac)
* all kinds of bug fixes

And this version brings Windows into line with the Mac release, feature wise. I'm sure there are still bugs to iron out but I think it should be more stable now.

Feedback welcome as always. Enjoy.

And a timely review at digitaldjtips =)
www.digitaldjtips.com

This program is great, appreciate your work. Is there any way you can add rename file names with the key info.?

Hey combo808

Theoretically, yes. But this is not something I want to implement; it's just too easy for someone to really screw up their library and blame KF. =)

Seriously, though, anyone with a serious filename schema (as opposed to just using tags) probably already has a copy of MediaRage or similar and can get it done with that, right?

Ib

THIS IS GOLD, thank you!!

I use this configuration:

snag.gy

And in ITCH I've made some smart crates for each minor key:

snag.gy

Each one of this crates have 4 filter, one filter for the same key, one for the previous key, one for the next key, and one for the major key (as I mostly have minor keys, I didn't bother in making smart crates for them).

The filters for the smart crate 4A looks like this:

snag.gy

Then if I'm playig a song and want every compatible song in my library I just browse to the corresponding smart crate (that is sorted by bpm) and I'm ready to go.

FANTASTIC!

Oh, I added a 0 before the keys because when I was doing the filter if I searched for 1A I would recieve: 1A and 11A

Oh, and I used the Windows version without any problem :D

I just changed the names of my smart crates to confuse other djs lol:

snag.gy

deejaysomething - in your opinion, besides being free, how do you think yours is better or different than beatunes or mixed in key?

Its useful to use for production purposes, re-naming helps organize the keyed loops.

@selkie: Glad you're getting some use out of it. Plus that's a creative application of smart crates, I like it.

@babooza69: being free-as-in-speech is more important than being free-as-in-beer I think; I've got nothing against people charging for software but it's best if it can be built on. Being open source is probably KF's main strength; if the algorithm is good now (and it seems anecdotally to be in the same league as the other packages), it can get better if someone smarter comes along to work on it!

@combo808: True. It's a feature I'd consider but I'm not big into it. We'll see how it goes.

hey deejay something,
thanks so much for this software i got it last week and it's been working great. One issue i came across yesterday was that I analysed a batch of files and for some reason the key tag won't change just for a certain batch of my songs - in KF it just says N/A in that column. he files can be analysed and if i change the settings to put the key in the comments tag it works fine but i'd like it to change the key tag which seems to be locked - do you know how i can override the lock? sorry if that's a stupid question.
thanks

Hey psalmon,
Those files don't support the Key tag. Not many formats do. See the FAQ on my site.

Good to know, thanks for the quick response - maybe i'll switch to the grouping tag.

life saver..... i was scratching ma head man! Thnx

@deejaysomething .... ur definately something 'god' ....(pun intended!)

Jeez...almost splashed out on MIK5 for vidz.... this is a god send.

does key finder write the key to mp4's.
I have been manually copying them over from my MIK5 scans when I have SSL open.

@djpuma_gemini
Not to the Key tag (see the FAQ on my site) but to Comment or Grouping, yeah.

In the interest of full disclosure, there is a possible bug with this; two users have reported tags being deleted from a few of their mp4 videos, but only on Windows so far, and very rarely. If you have a backup it shouldn't scare you. I'm investigating it at present.

For tracks that won't write to the key tag, I did the comment code as recommended, but then went into Scratch Live and sorted by the comment field. It was then a simple highlighting of the blocks of tracks that correspond to each key and mass-editing the key field. You have to do it 24 times, but it takes less than 10 minutes for the entire library.

Dope! I have the lastest version of MIK now and have been using it for a while now. Gonna try this out now :)

Back once again with the expected behaviour is KeyFinder v1.11, which you can get here: ibrahimshaath.co.uk

Features include:
* Mac OS 10.5 support (at least on Core 2 Duo)
* automatic update notification
* support for higher bit-depth (24-bit/32-bit) audio files
* fixed a segfault that was crashing the Windows build
* improved decoding for most Windows Media file formats
* proper logging solution on Windows
* improved memory management, greater stability
* drag and drop from Serato and Traktor (OK, that was in there before but I didn't realise it...)

Feedback welcome as always, especially if you've been waiting for the Leopard build; let me know how you get on. Is it working on Core Duo machines now?

Future features? I'm finally pretty happy with what KF can do but I've got a few ideas. Let me know if you have any new suggestions.

#thumbsup!

Yes, it does. Now I can use it directly on the MacBook I use for djing. Many thanks for this great piece of software!

The important things all work, but maybe these things would add a bit of comfort:
- It would be nice, if the columns remembered their width and their order could be changed.
- The ability to choose an iTunes playlist directly from within KeyFinder (e. g. per popup menu) would be great.
- Sometimes I missed the possibility to remove entries from the list (e. g. using backspace).

dope. extremely accurate and i love the GUI.

what's your paypal so i can give you a donation. i love when creativity and innovation is not stifled by corporate america and their bullshit.

Sweet. Great news.


Damn, those are really good ideas. =) The third is certainly doable and I'll research the other two.


Much appreciated, man, thank you. There's a little yellow Donate button in the left panel of my site ibrahimshaath.co.uk. I'm glad the app's working out for you.

Good morning sir, good afternoon madam, good evening all, how d'you do?

Any existing users should get an automatic notification, but here nonetheless is KeyFinder v1.12, which you can get from my site as usual: ibrahimshaath.co.uk

Features include:
* Automatic library integration with Serato, Traktor and iTunes (you can specify file paths in Preferences)
* The ability to remove rows from the drag and drop list, either with the Delete key or right-click menu

Beware: loading even short playlists from a large iTunes library can take a while. You may want to use other methods. But I thought I'd include it for the sake of completeness.

Feedback welcome as always.

How far is the mp4 support?

In what sense, nik?
MP4s work fine over here, both audio and video. There is an occasional bug re their metadata but it's hard to track down.
Are you having a particular issue?

Oops. Looks like I've missed it. Thought it could not do it properly.

What do you mean when saying you read the sl and traktor library?

For Serato, it will read subcrate and smartcrate files from a path relative to the database v2 file, and for Traktor, it will read the collection.nml file. In each case it will present them as playlists in the new library widget.

Not sure exactly how stable this feature is yet, but it works on all my test machines.

Ah, so your app is able to read and parse the database file and the crates files?

It doesn't read the Serato db, just the crates. That was painful enough =)

;-)

Hi, I'm getting the errors below when I attempt to run batch analysis on my serato crates, Serato Ver 2.3.3.7. Apparently your app does not point to the correct file location, however, I can drop them in the app and it works really great. Is there a way I can manually fix this issue?

My files are stored in F:\music\

Keyfinder V1.12 preference for Serato set to: F:/_Serato_/database V2

Log Excerpt:

2012-03-08 19:52:12.578 Debug: TagLib returned NULL File for /Music/Culture Shock Collection/Culture Shock Rock[Current]/The Police - Roxanne (135).mp3

2012-03-08 22:47:37.000 Critical: Failed to open audio file: /Music/X-Mix Collection/X-Mix ChartBusters/X-Mix - Chartbusters 24/Alacranes Musical - Por Amarte Asi.mp3 (-2)

That'll be the F: ... can you send me the crate file please? It's stored in a folder called subcrates; I should be able to fix it if I can see how Serato refers to the root when it's not C:

djsmthng, the path is always relative to the root of that drive. So a referenced file "/a/b/c/d/here.mp4" stored on the x: drive translates to

x:\a\b\c\d\here.mp4

Cheers nik, I figured it must be something like that.

Just thinking edge cases: I'm assuming, then, that it doesn't do crates that mix files from different mount points?

I'll try and patch it over the weekend, anyway.

@Johnny Cinco,
I got bored and patched the Windows version on the site, and it should take care of that bug. =)

Let me know if not.

Thanks Deejaysomething....It's works now....Great Job!!

Pretty much a computer dummy, can't get this to unzip, is it because I'm using 10.6.3?

slimmjimm, I just tested the zip file and it's fine, so yours may have corrupted. Please try downloading it again.

Snow Leopard is more than capable of running KeyFinder.

Got a full DL after a few tries. Thanks, my wife was giving me the stink eye for using both laptops.

Quick question, I might have skipped over it in the thread, are there any problems with analyzing .wl files?

I have absolutely no idea what a wl file is, sorry. I've certainly never tested one, but you might get lucky!

.wl is the file type for whitelabel.net seratos promo site

Ah, gotcha.
Well, if VLC can play it, KF should be able to analyse it. They use the same decoding library.

IIRC whitelabel files include an unencrypted lower quality version for most media players, right? If so, KF should use that for analysis. In theory.

the reason they asked is because MIK was corrupting .wl files because they are encoded differently. Im not really much a computer wizz, so I dont really understand other than unless u play them via erato they play @ 32kbs but with serato hardware plugged in @ 320. So i figure they were asking about the corruption issue? Maybe take a look on the .whitelabel forums & take a peek @ the thread about it. U will prob pick up more from there than u will from me.

Cheers Nicky, that sounds about right.
It's possible KF would have the same effect as MIK, but it all depends on whether wl files conform to the standards as implemented in TagLib and LibAV.

What about it slimmjimm - did it work on whitelabel files?

what ive been doing with whitelabel files is downloading them twice, run one set through, then manually tag the results of the fresh ones.

Seems to be working out ok so far.

Nicky, you mean making a copy instead of downloading twice right?

Seems to be working OK, not sure if some of the older ones retain their quality. I ran the MSTRKRFT remix of D.A.N.C.E and it seems kind of distorted, I have to find it on my backup drive and compare.

that distortion is exactly what we were talking about!

@ akiem, shamefully no! I actually did download it twice! lol wont be doing that again now tho!

:)

:)
sweet

hi i haven't used this before but am thinking about it after this trip i'm on, quick ? for mac - am i able to select an entire crate in serato or folder in itunes and scan all files and have it write key to tags?

I just got ahold of this a couple of weeks ago...

@deejaysomething
Thanks for this! You are the man!

Currently, you cannot pull files directly from itunes. BUT, you can pull the original music files outside of itunes and add it to the S/W

Actually, the most recent versions have some integration with other libraries, so you can analyse/tag the contents of an iTunes playlist or Serato crate. But you have to refresh the tags when you reenter the parent app.

I thought it was actually fucking with the file so it would not play @320, no idea there was distortion involved.

I mentioned probs with an older .wl file because I thought that Serato changed something so there would be no problems with MIK, was it the other way around?

Oi oi.
The new version 1.14 is up at ibrahimshaath.co.uk.

This includes:
* a slightly smarter GUI (you can resize the two panes, and it remembers where you left it)
* a bunch of bug fixes (including for iTunes Comment tags)
* by popular demand, the option to write keys to filenames. Do not come crying to me if you fuck up your library.

This version also marks the arrival of LibKeyFinder, a C++ library of KeyFinder's algorithm. This is open sourced under the GPL, so any geeks out there can integrate it into their own stuff.

As always, intelligent feedback gratefully received.

Thanyou! Love your work!

^^^^^opps Thankyou:)

Hi deejaysomething, just downloaded 1.14 for Windows and it is now writing both custom key codes and standard ones to the Comments and Keytag fields, even though I just have the option to write custom codes selected.

The program is awesome by the way!

Hello,

Great program, and much appreciated! Just wanted to bring up a few issues I've come across.

1. Running 1.14 on Win7/x64 with Core 2 Duo & 4GB Ram, I'm noticing that during a large batch job (400+) files, the memory usage of the program goes and stays up. After file 300 or so, the rest of the files started failing with Memory Errors, then the program crashed. Restarted, and ran the remaining files, and still noticed a large amount of memory committed to the program. Looks like a possible memory leak.

2. I've noticed that changing & saving preferences (such as switching between Serato DB files on different drives) doesn't take effect unless the program is restarted.

3. Drag & Drop functionality doesn't work, as dropping a file onto the program window has no effect.

4. Are Smart crates not supported?

5. Where are the preferences stored? I'm wondering if the Camelot Easymix codes I've entered into the Custom Codes will get saved when I install new revisions of the program.

Thanks again and great job!

-B.K.

Bizarre bug. My mistake, I know where it is and I'll try and get it patched in the next couple days.


Looks that way. I don't know where it's coming from but I think it's been in for a few versions. I'm on it, but debugging in Windows is horrible (there's no leak on Unix that I can see).


Prefs are applied as soon as possible; switching between serato dbs only needs a new batch window (ctrl+shift+N) to be applied. But I might look at changing that behaviour.


Errr, no idea. Works fine on my Windows VMs. But I'll take a look I guess.


I thought they were. Has there been a serato update? My smart crates load fine but I'm not exactly keeping up with SL at the moment.


Prefs are stored in the registry on Windows, I believe. I always try my best to ensure backwards compatibility with old preferences.

I am beginning to lose patience with developing for Windows. It takes (as an estimate) five times as long as for the Mac, and is no fun (important when you're not getting paid). Seriously, there must be a Windows dev out there who wants to take care of it...

Just uploaded a patched version. Download 1.14 again and you should be fine. Apologies for the daft bug.

I think you should work for Serato, see if you can sort them out to fix their bugs as quickly. Will download tonight and test it, great work, thanks.

All working as expected now. Great work, thanks for the quick fix.

Yeah, garbage collection isn't as automatic on Windows as it is in other platforms...Anyway, I compiled and ran your source code and found at least one culprit. In asynckeyprocess.cpp the audio object wasn't getting released after every file processed. Adding "delete audio;" before the return did the trick. I tested by running a large batch, and the memory usage isn't increasing nearly as much as it was before.



I see it now...Automatic reload would be useful for someone like me, with multiple DBs spread over both local & network drives.



This one may be related to the QT library version...I used 4.8.0 (VS2010 compatible) and it worked from the first build...yours are at 4.7.4.



My mistake - didn't realize that Serato stores the smart crates in the main DB (local drive) not the network drive on my setup. Though, possible new feature would be to show the distinction between Smart & Regular crates (like the blue/brown icons Serato has).



Cool!

Can't believe I missed that delete (and that valgrind didn't pick it up). Must've been when I switched to the library-ised KeyFinder. Good catch. That will probably be 99% of the memory problem as the audio objects get really big.


It's a headache though; you'd have to cycle through open windows, do validation to make sure you weren't interfering with running batches, yada yada. I might take a look at it. Feel free to patch it yourself though.


Actually drag and drop got worse in 4.8 on all my machines; it wouldn't accept symlinks any more. But if it works for you, cool.

1.15 is up at ibrahimshaath.co.uk

It includes:
* Custom sorting in the table widget; just click a column header
* Big dumb memory leak fixed - props to bkpsu =)
* Another couple of bugfixes

After scanning about 5000 mp4s last night I went to work and noticed I had corrupted a fair few mp4's, maybe 150 or so :( It was an older version of Keyfinder so not sure if you've fixed it but yeah, Thought I would let you know those tracks were playing in 2.3.3 before I scanned in keyfinder yesterday.

Oops didn't see to grab 1.15 but just started a batch job on about 4gb of new tunes and it seems to be running 3-5x faster than Mixed in Key

Feature suggestion: ability to automatically skip tracks over a certain length. I tend to dump a few new mixtapes into my library as Scratch Live is my primary audio player, and skipping over a few 40-120m mixes would've increased the batch analysis' speed dramatically (I could work around this, but I find it easier to just dump all of my downloaded tunes into a "new" folder then analyze that)

deejaysomething

thnx a lot for this cool app
the only thing I need help with is after "write key to a file"
I go to my SSL library how to integrate key to a "comments" or "key"?

and have u tried contacting Serato to sell ur app?

Sorry, I don't understand. Can you rephrase?

sorry
how to make it work with Serato Scratch Live?

Write the results to the file (I recommend the Grouping tag), then re-read the id3 tags in SL.

thanks for this!! way better then mixed in key worked faster and reads my serrate crates!!

yes Key Finder is dope!!!

thumbs up!

Cheers gents. Not been working on it at all in the last month or so; way too much Real Life happening. But it's energising to see that people are still getting into it.

Will sit down and try to fix the Windows build at some point; quite a few users having bizarre crash trouble. Plus I have a few plans for the future of the software.

I don't used software like this to DJ but it comes in very handy for doing remixes. Good work!

i hear you on that one good sir, i've been in the same boat with work. I downloaded the source code to tinker on windows but I realized Im several iterations behind lol. I'll set a reminder to check out the newest iteration of the source sometime this weekend and get to coding!

I wish I did something like this for my senior project in college but Digital DJing wasn't even mainstream back then, now I feel old.

Just wanted to say thank you deejaysomething for this great tool. I've never used Mixed In Key so I can't compare the two but your program works amazingly well and is very accurate from what I can see so far. I'm in the process of key tagging my entire library (crate by crate) and can't believe how quickly it's going by.

Kudos to you for writing a very nice piece of software. I will definitely be donating. Cheers.

^^ Real Talk

Could you please help me to make this cool app to write keys in to my Scratch Live

thnk you

deejaysomething... couple of things...

Firstly, awesome app, loving it. I'm on 32-bit and it now works pretty well for mp3's. My .mp4's however won't analyze program just closes after an error message. I'll post more about it later exactly what it says.

My other concern is and this is open to anyone, I use iTunes to organize my music library. Now I went through by dragging the artist folders from my iTunes/iTunes media/music folder. Now that I have my whole library scanned, what is recommended to scan new songs? Do I need to go through by dragging all of the artists folders to the program again? Will it re-write over songs that have already been tagged or can I turn this off? Just looking for an efficient way to go about tagging new songs without having the re-analyze the entire library.

"then re-read the id3 tags in SL" how to make this happen?

^^^ LOL click rescan tags?! :) box unplugged

=))))) super funny! долбаёб!

with the latest version 1.15 it will detect keys, but not not write them.

my steps
add a few files
click run batch analysis
KF finds keys
select all (ctrl-a)
right-click and select (Write tags to files) or click cmd-t
window pops up: Data Written to 0 tags and 0 filenames

this happens no matter which files i analyze. Also "Skip files.." is disabled.

Can you post a shot of your Preferences screen?

www.flickr.com

Thanks, that all looks good. Can you maybe email a couple of tracks it refuses to write to? I'll take a look as soon as I can.

does this work for aiff files?

If yes awesome, If not is there anything thats does?

Thank you this is awesome :)

possible for Konix or anyone to make a dumb it down type of vid for all the 'not confident enough, or lack of understanding folks'

sort of like the scratch tools/itch-sync vids.

thanks

This is so awsome, drag and drop from serato is great! Thank you so much!
if it would work with .m4a files from itunesstore it would be even more awsome. Now I convert those files to mp3 just to check the key and then manually add it to the .m4a tag.

^^^^ If I'm understanding correctly, you can drag and drop the files from serato, so say if I go through the files tab in ssl then locate my music folder(s) just drag those to KF and it will tag em and write to the file, then obviously I would need to rescan tags correct?

the problem only occurs with tracks on the secondary hd. Tracks on the primary hd write just fine. the permissions of the parent folders on both drives are exactly the same djnyce: read+write

There is an option (set in preferences) to ignore files that already have a value in the comment field. Also, I had issues with the app running on four cpu's and changed it to just use one (set in preferences) and the app does not crash.

still love this app!

ibrahim does this work with flac & aiff? or anyone else who uses it???

Working great for .mp3's but keep getting the error for .mp4's "Failed: Could not open audio file (-2)" I suppose can do the mp3 and then tag manually as a workaround, great product loving it! Just wish it could scan .mp4's too!

Hey Solidsnake. Under normal conditions, KF has no trouble with mp4s. Can you send me an example file so I can take a closer look?

Maybe also check what the KF log says about those files.

I'm on 10.6.8, on a 32-bit MacBook Pro. I'm using music video (mp4) files from SmashVidz or well now VJ-Pro. Key Finder - Version 1.15. Basically I see my Serato Crate playlists, I open them, click Run Batch Analysis the files turn red and I get a message under Detected Key "Failed: Could not open audio file (-2)". How would I go about checking the log?

It's in ~/Library/Logs/KeyFinder.log IIRC.

And do please send me one of the videos that doesn't work for debugging.

just found this, going to try it on windows vista!

Yup.

sweet. thanks dude.

nice app!

KeyFinder v1.16 is now up at ibrahimshaath.co.uk. There is now also a US mirror, kindly hosted in Dallas TX by a generous user; just click on the appropriate flag =)

This version includes:
* Prepend/append options for writing metadata
* Option to skip tracks over a certain length (for avoiding mixes/audiobooks/whatever)
* Improved logic for skipping tracks that already have keys
* Updated library binaries
* Improved Linux support
* Multiple bug fixes etc

So, this is the first update in a while, because most of the feedback I've been getting has been related to memory allocation problems affecting a minority of Windows users. Those issues are not fixed, and are unlikely to be in the near future. I've spent as long on them as I'm willing to at the moment. So I'm afraid the Windows build will only improve in reliability if another developer picks it up or I get a second wind.

Also, since the last update I got to the bottom of a lot of the "KF has deleted my tags" issues that were raised, again primarily by Windows users. TagLib (which KF uses for all tag reading and writing) will overwrite any ID3 v2.x tags with v2.4, but v2.4 isn't read properly by Windows Explorer or (I think) WMP, or a few other apps.
If you use kid3 (it's free, just Google it) to check the tags on your tracks you'll see that no data has been removed, it's just been translated to an updated tag version. If this is a problem you can just convert back to v2.3 with iTunes or something.

Onward and upward. Hope this helps people out; any feedback welcome.

Bravo. Thanks dude

simple yes or no as i haven't tried this app yet but plan to soon - is it possible to select/choose tracks via itunes and/or serato, have it scan for keys, and have keys automatically write to tags that are displayed in itunes and/or serato?

ok i just installed it and nothing is working well

1. is there a way, instead of batch, to select like lets say 10 to analyze from a playlist or crate?
2. i added the Camelot codes in preferences, but when i scan it still shows as the default letters
3. i enabled overwriting to keys tags, but i log into serato and it still doesn't display key

help!!

i guess you can try selecting tracks in serato, then just drag it into a new folder - then in keyfinder, just analyze that folder




in the preference, there's an option to write keys to file - the default is no so you need to turn it on




in serato, you need to rescan id3 tags (its in the files tab)

now i got a question, somehow, keyfinder cannot write to my MP4 files (but it can detect the key). i already check the mp4 file properties and its all read/write. and in serato, i can easily change key and it writes....

and keyfinder doesnt work with whitelable files (?)

Yeah, or drag the files directly from Serato. There are many many ways you could do it.


Plus make sure you have set "What to write"; its default is just to write the Keys.


Are you trying to write to the Key tag? Because mp4 files don't have one. See the FAQ on my site. If not, provide a bit more detail, like a screenshot of your preferences and an example file, and I'll take a look.


My understanding was that it can analyse them but it tends to corrupt the high quality version if you write to the tags or whatever. But I don't know, I don't have any whitelabel files.

Are you trying to write to the Key tag? Because mp4 files don't have one. See the FAQ on my site. If not, provide a bit more detail, like a screenshot of your preferences and an example file, and I'll take a look.


I usually make it write to grouping tags and manually write to Key tag in serato

Long. I use a 3rd party app to automatically batch copy from one tag field to another. Perhaps KF could include this option as standard?

Also, Serato really ought to give you a few Whitelabel files for testing.

Not sure I understand. The Key field does not exist in the mp4's metadata*, it only exists in Serato's database. So a batch copy would have to take place in Serato.

* Some apps hack it into a 'field' called com.apple.iTunes:initialkey, which I may start doing, but it's still not supported by Serato if I recall correctly.

It does, however, exist as a entry field for ID3v2.3 (and 2.4). Not only that, but Serato Software actually reads that field.

Which is why it's in the KeyFinder software at all =)

Im just curious to this. Is it the same for AAC and ALAC files or do they have the Key Field?

Anything that uses iTunes metadata (atoms) rather than ID3 or some other tagging standard. So, yeah.

Sorry, yeah it's the same for those filetypes; they lack the key field.

<shakes fist at no edit function>

That kind of puzzles me. Dont get me wrong I believe what your saying! I still use mixed in key, and here is why: They actually write the key code to both AAC and ALAC files to be read in Scratch Live.
(no itunes interaction) This from the MIK5 version. So theyve must have found some kind of workaround....

SSL previously had tag-issues, both read, write & crashes especially when it come to AAC & ALAC, but seems mostly to be sorted as of version 2.4.2.

Traditionally, Ive always played 320k out, but I keep my master music archive in Apple Lossles.
Now considering running ALAC throught the whole "pipeline", as HDs are getting bigger and with the recent improvements in SSL.

Yeah, I do ALAC for the whole workflow.
OK, so I guess Serato has been brought into line with MIK's hack. So I may emulate their hack (and update my Serato!) for the next version.

Ah yes, I just found this post. serato.com

OK, I'll get that fixed for next release. Should reduce the amount of confusion =)

Anyone running KF on Mountain Lion? Any problems?

Also I'm working on making the interface localisable, if anyone's interested in translating the program's strings into other languages?

I used it once on Mountain Lion with no problems. :)

Great, thanks.
I'm just thinking; I'm probably not gonna get registered with Apple to sign the app (partly to save money, partly to avoid XCode, and partly to protest their silly software lockdown), so you guys will need to tell Mountain Lion to allow unsigned apps for future releases.

Thanks again, this is a great app!

Running on mountain lion great. No majors issues other than the problem with Secondary hdd. Any fix or workaround yet?

Sorry to be a dummy...

So G Flat and F Sharp are essentially the same thing?

Also, thanks for this. Seems like a great piece of kit so far! I'm completely new to this harmonic mixing stuff so am interested to see how it all pans out.

Anyone having any luck using this for HIp Hop, R&B, Old School, Pop? Great tool, I will definitely donate if I can use this with the genres I spin.

Yup.

F# = Gb
G# = Ab
A# = Bb
C# = Db
D# = Eb

Thanks, makes sense now. I really need to read my music theory books!

Just a question. The software only shows my Serato crates, not my iTunes playlists. However in preferences it knows where the iTunes library is so I'm wondering if my iTunes library should be displayed?

Also, In the batch window, if I drag a file from a serato crate it will scan and write tags fine. However if I drag a load of songs from the iTunes window it will scan them and identify the key, but doesn't write anything to the comments field.

Should it be?

I just downloaded KF and immediately put it to work. I imported my entire drum'n'bass library of almost 400 songs and detected the key for half of them. I decided to check my results against RE3, Beatport, and a DJay app I got from apple (all of which I use for bpm and key detection)(I use serato and CDJ's btw). I know that all of the programs can't be correct 100% of the time... that being said, I am getting so many different answers it is making my head spin... RE3 gives me one answer, Beatport and my weak-as-hell DJay app usually give me the same answer (oddly enough), and KF gives me another answer as well. Sometimes they are all on the same page but not enough to be able to pick a favorite.

Am I just being too picky and do I need to just pick one and trust it to be incorrect but consistently incorrect (if you get what I mean)? Should I go with whatever key appears in at least 2 of the programs? I know some music theory but I can't key out every scale on the piano. That would be so cool though (I think I might learn).

Anyways, thanks a lot for the program!! I do like how user friendly it is... Except for the Advanced tab in the setting made me feel like an idiot but I am sure most DJ's don't have a clue what some of that stuff means either! It would be great if you put some of that stuff into english ;-) I'm over here learning about spectrum analysis and science! WOW!

I guess a good question would be how to set my temporal window, hop and frame size for bass heavy music? ... but that was after 10 minutes of research so it could be a dumb question... Is it a good idea to bump the starting frequency up to A220 (I figure not too many songs have roots under there)? How about decreasing the # of octaves? Would that help me get more correct readings from KF? I am not even gonna guess what bands per semitone, downsample factor, classification, or segmentation do...anyways I am going to sleep now! I hope you get back to me!

Exactly. Any one app will (if it's accurate enough) pick out decent compatibility, whether it gets the exact key right or not.


I'm a drum and bass DJ myself, and all the default settings work fine. You certainly don't want to raise the starting frequency given the importance of the bassline in determining the tonality. Again, it may not be 100% accurate but if you just trust it, it very rarely lets you down. =)

No idea; if you send me your library file I'll take a look.


That shouldn't be relevant; if it can scan it, then it can get to the file to write it. Is there anything else to tell the two cases apart?

Thanks dude!! Any chance you could add BPM detection to a future update? I only have 4 sources for this, I could always use a fifth opinion!

please don't....it works great just the way it is.

Curious about this one :D

Well you can keep your version of KeyFinder without BPM detection (since it works so great)... IMO it isn't as good as RE3 because it is just as inconsistent and doesn't give me the BPM. Not to mention it is more important (IMO) to know the BPM of a song than to know the key. Either way, I will be ok. It would just be great if I had software that would write the BPM AND key into iTunes. Save me some time, although I'm still going to check it on RE3, Beatport, DJay, and tapping it out.

Wait, there's a 3rd installation of Rapid Evolution? Might have to check that out.

Beta version

Good evening.

KeyFinder v1.17 is now up at ibrahimshaath.co.uk.

This version includes:
* Hack for the key tag in iTunes metadata (AAC, ALAC etc)
* Localisable interface, with translations for French and Swedish users: more to follow.
* Updated library binaries
* Various small changes

As always, any feedback welcome. And if you have the linguistic chops to write a translation of the GUI into your language, let me know (it's easy; no programming knowledge is required).

This release also marks KeyFinder's first birthday! I launched it a year ago today, with the post at the top of this very thread. After a slow start, it's been downloaded more than 5000 times in its first year, by users in 120 countries. I've been thoroughly humbled by the response to my little app, and having it used by hundreds of DJs has been very rewarding. I've also had tons of feedback, which has been fascinating at least as many times as it's been infuriating. So in short, thank you all so much for your support!

And if you want to thank me in return, why not drop a small PayPal donation alongside your next download, so I can celebrate this auspicious occasion in some style? In return, I promise to howl at the moon the names of any forum members who donate, at the end of a night of raucous drinking. =)

Hell Yeah, Thanks!!!
Will start testing next week, kinda looking forward to wave MIK bye bye ;D

Great Product.

Pointed to the wrong library file. Works well now! Although the iTunes playlists take quite a while to populate compared to serato crates but it's not a biggie.

One thing I'd really love to see would be the support of playlist folders and subcrates. So I could scan my whole house folder at once, instead of having to scan each playlist individually within that folder.

Thanks for all your hard work though, such a great tool!

Great Software first off but I can't seem to get it to write to my id3 tags in Serato...I don't use itunes library so that is no issue...I ran by batch it saw my crates it processed my crates but didn't update the tags...Am I doing it wrong?...Thanks again even if it never writes to them it is great stuff for my Ableton as well....

Did you tell it to write to the files? Either set automatic writing in the Preferences (as well as deciding what tag you want it to write to) or select the files you want to write to and hit Cmd+T (or Ctrl+T on Windows).

Thanks for the quick get back...The workflow I used is this:
In Preferences chose what to write - Keys
Where to write - Key Tag Overwrite
Dragged files from crates
Ran batch process
When complete rescanned files in Serato

Nothing in the key tag file
Also ran a batch with the preference to append file name and that also didn't take...I am on a Macbook pro running Lion and Serato 2.4.3

Again thanks for the tech support....

Yeah, so looks like you need to write the tags. Read my post again =)

Command T did the trick thanks again...I will drop a couple of beers in your paypal....

So I've been using Keyfinder for a while now, slowly 'keying' my entire library. Well, I've recently come up to the FLAC folders. Did I totally miss this, because Keyfinder won't write to any of my FLAC files? Sure, it will detect the key, but refuses to write to the file.

Am I doing something wrong?

Macbook Pro (early 2011) running 10.6.8

FLAC files don't use ID3 tags.

keyfinder corrupts mp4 files! so after analyzing, then writing the key field, the mp4 got the corrupted icon in ssl 2.4.2.

solution, just analyze the key, then write the key MANUALLY in ssl.

Way to not be at all alarmist. Maybe you could send me a bug report rather than freaking out?

FLAC files don't use ID3 tags, but KeyFinder is not limited to ID3 tags. In fact my tests write to FLACs fine. Can you send me your log and maybe an example file blackavenger?

sure, and thank you for the prompt reply. i'll get that out to you as soon as I can.

so what can i send to you? original mp4 file and the corrupt? where can i find the keyfinder log again?

it just corrupted 35 files so...

My error. I did not realise keyfinder could write to Vorbis Comments :)

So I just tried to write the key to the "comment" tag, and it worked. Unless sending you the log & example file will enable me to write to the Key or Grouping fields, I suppose I now have my solution.

Out of curiosity, can someone explain this to me? If FLAC doesn't write ID3 tags, how is it that I can attach Album Art to FLACs? Where is the Art saved? Obviously, I am ABSOLUTELY ignorant to all of this. Thanks.

Really, you're able to attach artwork for Flac in SSL?

Oh, no.....I can't get the Album Art to show up in ScratchLIVE. But it will show up in the players on my computers (Win7 - JetAudio .... OSX - Audirvana Plus)

Ah, you mis-understood what I was saying (though you are correct that you can place it in the comments field).

Vorbis comment is a container (much like ID3) for metadeta in file formats. These formats include Vorbis (audio codec commonly contained in .ogg files), FLAC (self-explanatory), Theora (video codec commonly used in .ogg files), etc.

For all intents and purposes, it is a header for information. After popular demand, Xiph (maintainers of such codecs and the vorbis comment metadata container) added support for a metadeta field for album art (wiki.xiph.org).

it does corrupt files if you set the mixed in key preferences to write the info in the key tag of the mp4, thats why you should set it to write the key to the comment tag and then copy n paste in the key tag from within SL.

^thx man - will try that

I skimmed trough the comments looking for a answer for my mp4 corrupt file problem.

I freq. record vinyl and after that I cut the noise before and after the tune and fix the (mostly minor) swing the BPM has over the full duration of a tune. Then I save them as AIFF and convert them to mp4.
But Last week I started to have some problems with using Keyfinder. So what I do now is use Keyfinder first and convert them after and I don't have the corruption problem.

And iTunes reads the comment files just fine. Dunno if this helps anyone, but since I have been struggling for some time, I thought I post it here.

Suggestion (and by all means, if this already exists, forgive me and point me in the right direction):

I was working on a Mac that I don't normally use. I installed KF, analysed my tracks and wrote the keys. Then did a bunch of other stuff like MP3Gain etc. Next, I took them into SDJ to analyse them and build overviews etc and quickly realised that I hadn't set up the KF preferences to write to the key tag field - everything was written in the comments. So of course I had to re-do the whole lot all over again.

It occured to me that if KF had an option to copy from one field to another, I could have avoided having to do this.

I did think of using a tag editor like Tag&Rename but that would have meant a) taking everything back onto a PC just for that and b) of the fields we're concerned with here, it only handles two of them (comments and grouping) so it was basically quicker to re-do them, but it would have been even quicker if the copying option was available in KF.

Bottom line is: I should have taken more time to carefully check what I was doing and set all the preferences up before using the app. I think it speaks volumes for the ease-of-use of the softwre that I've got so used to having 'set it and forget it' that this time I really did.

Thankfully, I didn't really have anything in the comments tags that I didn't mind losing or this would have been a complete disaster!

And thanks for such a great app btw. I never really liked MIK and am so glad I don't have to use it.

Anyways, just a thought.

@Marv

I don't plan to add this kind of thing to KeyFinder, for a couple of reasons. First is that the tag-writing library appears to be the flakiest part (at least on Mac) and the second is that there's loads of general purpose tagging apps out there already so it would be a bit redundant.

All the best. Glad you're getting some use from KF.

Marv, you might wanna look into media rage for mac, not entirely sure, but it might be able to move the tags from comments to the key field. If not, sort your tracks by the comment field in SDJ/SSL, then select all tracks with commet 12A, and add all those into the key field at once. A little work, but still, thats only 24 entry´s, and your´e done.

Everytime when you add tracks to your library... ouch :(

No, not really; conflating two issues =) KF will happily write to the Key tag if you tell it to.

Thanks for all the replies guys.
As deejaysomething said; fact is, this wouldn't have been a problem if I'd remembered to set up the preferences beforehand. It's just that once it had happened, I figured it would have been easier to copy and re-write within KF rather than re-analysing and re-writing. Not many tag editors write to the key field, so since KF already does, it would be helpful if it also copied.
Anyway, not a major issue. I was only working with 1,000 tracks and it didn't take long on my iMac.

I do need a mac-based tag editor and media rage does look good so thanks for that WarpNote. However, over the years I've built up a range of really powerful tools for the PC that I doubt I'd surpass on a Mac, which is why I still do . Even with these tools, I have to use a combination because no one tool does everything I need to and none of them do everything they ought to do (IMO). Like Tag&Rename for example. The 'copy from one field to another' function is awesome, but the fact I'm limited to a small selection of what's possible isn't so cool. I've tried writing to the developer, but I've never had any response either, which kinda sucks because I've bought, supported and recommended the program over many years now.

Actually, I'm getting a bit fed up with apps/developers that ignore their user's needs or feedback, which is also why I'm impressed with you and your app. Well done and keep up the good work.

p.s. I should have mentioned earlier that I used to use Rapid Evolution to do my keying, which I was happy enough with until KeyFinder came along, which does the job more easily, more quickly and more reliably in my experience.

I'm having an issue with v1.17. it seems to be messing with my MP3 tags, for some reason it is shortening my song titles to only 30 characters, but I'm only noticing this in windows media player, i rescanned my tags in SL 2.4.3 and its showing up with the original full tag. no clue whats going on but I'm going to restore everything from my back up drive since i have a gig this weekend and don't want any surprises.

Anyone else have that issue?

@Dac I've not seen any reports of this. Windows is badly behaved when it comes to ID3 tags. Try converting the ID3 version from 2.4 back to 2.3 (e.g. in iTunes) and hopefully WMP will read everything fine again.

I'm looking at making the tagging library leave older versions of tags intact, rather than automatically upgrading them beyond Windows' antiquated skills. That may be in the next version.

^ that would explain it then. when i get some time i will try to convert them back. I love the program though! thanks for the response!

Huh. Traktor now includes key detection; they sneaked it into the latest point release. It's a damn good algorithm too; I'm gonna have to up my game =)

Wow! Serato should implement your algorithm!

I agree =)

So do I.

Congrats!!!

www.djtechtools.com

Oh! you made the chart! sneaky you!

deejaysomething's key detection + Nick's MixEmergency + Serato's Pitch 'n Time + Serato Scratch Live + Serato DJ = all-in-one DJ software I could get behind. Traktor is pulling away, fast. Key detection, remix decks, IPAD APP, I mean it's sink or swim time now folks

^ indeed ^

Hi, I am running across an issue where the tags (title/artist) are removed from mp4 files. This occurs using version 1.15 and 1.17.

Yeah, one other user has reported this issue, it's tracked on the GitHub site. I can't recreate it at present.

well, if this is useful for someone, I use mp3tag v2.54 and Keyfinder 1.17 (on XP), with no problem (tagging on grouping tab)

Im going to try this on my Win XP and report back, however, im running into this issue on Windows 7.........I use the mp3tag as well and have tried several methods between using keyfinder and mp3tag. If I use use mp3tag first it adds the title/artist but keyfinder then deletes them. If I use keyfinder first then use mp3tag the key grouping comment is removed when it adds the title/artist tags.

Is Keytag writing ID3v2.4 tags?

can u upload one of that mp3 files?? , i would like to take a look

(in fact ,i have seven ultimate and snow leopard on different machines)

I tried it on Win XP and got the same results as Win 7 using keyfinder 1.15 and 1.17. The issue does not occur for all mp4 files, just some. I use the mp4tag to reset the title/artist and manually have to set the key value since key finder doesn't add it. I tried using ID3v2.4 but it still provided same results.

The issue is only with video mp4 files and not mp3s. If you still want to try let me know.

why not? yes of course! :)

works great for me

wow after lookin in to MIK (at a cost lol) i stumbled upon this and boy i think it does a good job...Its even improved virtual dj with whole array of new chords lol. Well I be moving onto the new ddj sx with the serato software when ever the boats come in! (delays with shipment). Now i do like virtual dj as it was for me a good introduction into harmonic mixing - i appreciate it had it limitations but for me i could notice a real difference when two harmonically linked tunes were mixed together. I really think harmonic mixing is important and was wondering weather the serato software will have the chord displayed some where as i heard it will display the chord with MIK. This may sound obvious but I have never used serato.

I hope you got a first for all your hard efforts lol

Serato does show the Key if that's what

Serato does show the Key if that's what you are referring too. I suggest you download itch or Serato DJ and start becoming familiar with its operation prior to getting the SX as it will make the functionality of that unit easier to use. Also, if you are looking for a way to automate the adding of the first cue read my serato.com.

Help me, Serato forum, you're my only hope!

KeyFinder 1.18 is coming along great; in fact I would have released it a couple of months ago, but I just don't have the time or the skill to keep the Windows version going, and I'd rather not get out of sync with the Mac release.

So, if you are (or you know) a Windows developer with Qt experience, or a cross-compilation guru, please get in touch via the link on the website! The future of the Windows port depends on you!

For the rest of you, I hope to have a swanky new version available soon.

ibrahimshaath.co.uk

Somebody please!

This program is amazingly good and would love to see someone help keep it up.

Lookin' forward to the new Mac update.

That's what made me search for "Serato Key Detection" and I came across this thread. I went to download your program, but when I clicked the US flag next to the latest version, it took me to this link: keyfinder.baw.la

Same here. Tried the UK version and it downloaded but wouldn't unzip.

ibrahimshaath.co.uk

Just click on the UK Flag, download accordingly.

Ah, OK. The US hosting was provided by a generous user; I'll send him a message.

Indeed.

amazing program and fast! Just donated.

Doing my first batch now. Thanks to DJ @Combo808 for suggesting this application.

Still nothing on whitelabels? There's a few other files that it don't seem to write too either...

Hey hey. Very sorry for the long silence, but the new version 1.18 is up at ibrahimshaath.co.uk, for Mac only.

This includes:
* a slightly faster analysis process, with a much, much smaller memory footprint; it should be easier to run KF alongside other apps now (although it's still very CPU intensive, obviously)
* a hack for the key tag in FLAC files, using the de facto standard among DJ apps
* the preservation of ID3 v2.3 tags, rather than automatically upgrading them to v2.4
* lots of new localisations
* a load of bug fixes and minor new features.

The delay has been largely due to my working with a DJ software house to integrate the KeyFinder algorithm into their packages. The upside of this means that all the improvements I've made for them get passed on to you!

Also... this release is not for Windows. I still haven't got the time or the interest to do the Windows work, so it may be a long time coming unless a Windows dev steps up to help out. Sorry about that.

All intelligent feedback gratefully received.

^ NICE ^

Good to see you haven't abandoned this project.

+1 Thanks

Thanx

+1, Thanks a bunch, it is very helpful

...now if only it was Serato that was using Keyfinder built in :(

+10000

Right, here are two things I didn't expect to be saying quite so soon:

* KeyFinder 1.19 is now available at ibrahimshaath.co.uk. It's just a patch release, I found a weird bug with certain decoders.

* After many, many hours of poking and prodding, it's available for Windows, sort of. As always, I can't guarantee complete compatibility, or even that it'll work on your machine. It doesn't work on my old XP laptop. But hopefully it's better than nothing; give it a try and see how you get on.

on version 1.18 & 1.19...i cant see the crates of serato, reinstalling the 1.17 version, I can see again the crates,
also try uninstalling the version 1.17 ... and then install the new version ... but with the same results
nice adiction , the automatic selection of language...but i would like to select english as default.

OS X 10.8.4

thanks! great great software..much appreciated !

Very weird. That code hasn't changed substantively since last August, and I can't recreate it. Can you send me your serato database file, please?

Anyone who had an immediate crash from yesterday's Windows build, please try downloading again, I've added some missed dependencies to the package. Works on all my Windows boxes now.

Yo DeeJay Somthing,

Live the software, but had instant crashes on MAC too with the new software, so I re-installed the 1.17 version and it worked. BUT all the new mp4s i tagged are now corrupt. iTunes plays them, finder plays them, but Serato is showing they are corrupt. It shows the broken iTunes link in serato. Is there any way to fix this quickly? I was planning using most of those new track tonight!

Please get back to me asap.

Yes, I had Mac crashes too yesterday too while doing videos - need to look and see if I can revert back to 1.17 - hope i saved it.

Sorry man, I've got no idea. There have been issues with mp4 tags in the past but it's never been possible to recreate them. Do you have a backup? If you could send me an example file (preferably two copies, before and after) that would help me to check it out.

As for the crash, did either of you get a log from OSX? I can't do anything about it without more data.

Oh, also, which version of OSX are you guys using? I removed some compatibility for 10.5 in this version, given its age; maybe this is related to that.

My OS is 10.8.4, all updated and fresh. I downloaded the files, then ran them through your keyfinder software before copying them into iTunes. So, there is no before and after unfortunatly for me. Otherwise this would not be such an issue. I can send you one of the corrupted files if you like.

As far as the program instantly crashing, I didnt bother getting the report. It was probably cause I was running like 200 files at once. The 1.18 also gives this error for all the video files: "Exception: Frame rate must be > 0". Version 1.17 works fine, but then again that is the version that corrupted the files. Only Serato cannot read it though... Any ideas on what I should do (aside from re-downloading them all)???? :-/

Just counted and it messed up 81 new files. I did check my old video files that I key tagged and they are fine...

Mac OS 10.6.8 here...

I'm went back to a older version and making sure I don't corrupt anything...

Testing now

Any word on my Files?

No, I didn't keep a backup of your files. That's your job, man.

I think I have an idea of what's causing both the bugs you're experiencing, but they won't be immediate fixes. Top of my todo list though.

Can one of you please recreate the immediate crash and send me the crash log? I have no hope of fixing it otherwise.

Cheers
Ibsh

Ill try to recreate the crash and send u the log.

As for my files, i was not asking u for a backup. And my files are backed up! But this time i keyd them before i copied them. So the backup is just as corupted as the originals... Its not that big a deal, just want to make sure it does not happen in the future. Ill def copy the files first, then key them going forward.

Cool =) let me know when you have a crash log.

Incidentally, have you tried using a tag editor (maybe kid3) to completely remove the tags from the corrupted files? KF doesn't do anything at all to the audio streams so any corruption will be in the headers/tags in theory.

I've fixed the "Exception: Frame rate must be > 0" issue with video files, that'll be in the next release.

sorry for delay !
Now I see the database, there are many songs that I had already deleted .... will try renaming the database.

please, take a look, thanks in advance!

OK, here goes.

KeyFinder 1.20 is now available at ibrahimshaath.co.uk

This version allows you to write to the Title, Artist and Album tags, which has often been requested, though I do not know why =)
It also fixes the frame rate exception with video files, and should no longer corrupt mp4 tags.

Thats GREAT! I am gunna try it out asap. Ill get back to you to tell you if it fixed my files!

Thanks for getting on this so quickly.

It won't retroactively fix files, but it shouldn't break any more.

Like I said, you should use a decent tag editor to completely strip the tags; that'll fix the files.

1st, stripping the tags did not help, but read on, I think I have the answer as to why. Ill take you through the process:

Okay, I finally got some time to run some tests. The issue I was having was with mp4 video files, not mp3s, important to remember. My question in my head was, why did this f-up my new files, but my old files were fine when I tagged them (thank god). So, here is what I did. First I re-downloaded all the tracks, i was able to find a semi easy way. That renamed them in my folder to "track name (1)" in my download folder.

I took that, made a local copy on the desktop, then ran that through Keyfinder. Put it in my iTunes and fired up Serato. Just as I though, Serato would not play the file. Then, I ditched the copied file. And I copied the original version back to the desktop, added it into itunes, opened Serato, and the file Still would not play, even though it was not the version I put through Key Finder. Fishy right? It had the same problem but was not tagged.

Next, I made 1 more copy, this time I put a (2) at the end, to change the name/what Serato's database would be looking for. I then dragged it into iTunes, opened Serato and the file played just fine. Going one step further on this test (after closing Serato), I ran the same (2) file that was in my iTunes Playlist through the keyfinder software. I opened Serato, and it played the file just fine and had the key tags in all the right places (Key, Comment, and Grouping. Overkill, but I was testing).

So, my theory is that if you run the file through Keyfinder before Serato, somehow it corrupts the file and is saved in the database forever as a broken file. If you analyze it in Serato first, then run key finder, the file is totally fine. I think that its writing something bad to the Serato database, maybe a piece of the new key information is getting pre-written to the file and when Serato databases the file after the fact, it breaks the database link. Like for instance, this is not real code, but it needs to be mp4file.serato.keyfinderInfo, but if you key it first its this: mp4file.keyfinderInfo.serato, thus permanently breaking any possibility Serato could ever read the file. Cause it will always reference the bad code as long as the file's name has not changed.

Do you understand, am I making sense? Im no programmer, haha. What do you think?

one more thought...
I'd bet, if i pointed to a fake serato database (for new mp4 songs), keyed a song, added it to iTunes, then analyzed it in Serato, it would work because Serato would read all the pre-existing tags on its own, without a pre-written database log. On the flip side, if I keyed any pre-existing Serato files, their new tags would not be saved in the actual database... Just a guess, but it kinda makes sense.

ooooohhhh, one more thought
Can you talk to the Serato people, get them to integrate this with their software. Your batch analysis is super similar to Serato's. Seems silly not for Serato to key tag songs, Tractor and Recordbox do. Just food for thought, but it would be the bomb if you did! :-)

Yeah, the old version of KF was writing some bad data immediately after the MP4 tags, which may have overwritten part of the Serato tags. I wouldn't expect it to happen any longer with KF 1.20 though; is that your experience?

And as for inclusion in Serato, I wrote to them recently but got no reply as yet; if you want to write to them separately I think it could only help =)

I was using the newest version you just updated for these tests, not the older ones.

And yeah, I will make the suggestion. I would ask everyone that is still reading this forum to do that. Its dumb that they dont have a key detection when you analyze your files.

I noticed something interested in 1.15 and 1.17 which may be attributable.......the id tags are set to version id3v2.4.......and i see that windows 7 and Serato dont show the title/artist unless it is id3v2.3 or lower. To fix the issue i use a program called mp3tag. My question is......can the setting be changed or added in the program.

I'm pretty sure Serato can read ID3 v2.4. I know Windows Explorer and WMP can't, but they're in the minority.
In any case, more recent versions of KeyFinder will not overwrite ID3 v2.3 with v2.4. Try the latest version and see how you get on.

v1.21 is up at ibrahimshaath.co.uk

It fixes a few memory leaks, and a bug with the cmd+comma sequence on Mac localisations.
Everything else is background stuff to make my life easier, and will hopefully lead to fewer bugs in the future =)

What does "cannot prepend audio data with a different frame rate mean" and how do I go around it?

It means either that you've found a bug or that you've got a strangely malformed or corrupt file. Can you send it to me, please?

Cheers.

FYI, Scratch Live software works a lot better with ID3 v2.3 than v2.4....
serato.com

Sure thing; that's why I've tried to preserve it in recent versions rather than upgrading to 2.4 =)

Just mentioning it, as I've had quite a few isues with v2.4 tags :)

Everything does, which is funny for a spec that's been around shy of 13 years.

Oh don't get me wrong. ID3v2.4 is an utter pain in the ass, and due to the non compatibility with practically everything, it's broken a fair share of my own files (I'm looking at you Traktor - who had a nasty habit of retagging everything it touched).

via e-mail or...?

Yeah, via email. There's a contact link on the download site.

Trying out the program. Getting an error: Exception: Could not open audio file (-2). All my music is in an external drive and I've changed the database location accordingly. Any clue..

thanks

me too..... need help with this issue

Could you guys let me know which library you're reading from (I assume Serato?), and also send me the library file? Cheers.

Yeah. I'm using serato. I have a 200+ gig library and its not seeing any of them. How do I send you some files???

Thanks for the quick response.

also it will not pull up my itunes at all .... it just "LOADING" but the tracks never appear.

I have the program reading my _Serato_ and my itunes XML files that are located in my external drive.

this is the pathway to my database folder: /Volumes/DJ DRIVE/_Serato_/database V2

Ok, I just need the Serato and iTunes database files, send them via the contact link on my site. Thanks.

will do when i get back to my computer

sent

thanks

sent as well...

hope it helps....


thanx

Stupid question but anyone having trouble with keyfinder quitting on whitelabel files? I know ppl couldn't write to the file but some of the files are totally crashing the prog.

That may be to do with a bug I fixed yesterday; fix will be in the next release. But, as usual, send me the file if you want me to recreate the issue.

Hi Deejaysoemthing

Been using KeyFinder for a long time now on Windows and I think it is a fantastic program. The latest version has a strange issue. Normally I have an album in a single folder with all the MP3's along with the cover art JPG and a track listing text file. Previously I could drag the whole folder into KeyFinder and it would ignore non music files. Now if I do that it crashes the program, it will only work if I only drag the MP3 / M4A files into the window.

Ah, that's no good. I'll look into it. Again, I think that's probably associated with a bug fixed earlier in the week.

Great, thanks.

Right; EdT2000 and Good Times, the crashes you noticed are definitely fixed in the next version; I had fixed it already. Should be up sometime at the weekend.

I'm gonna prioritise decoding tests to ensure this bug doesn't creep back in.

Great work, thanks. Any chance of getting analysing from iTunes playlists/Serato crates working properly on the Windows version. This has never worked for me, it has always crashed the app when you try and analyse the files.

Could you send me some detail? Paths, database XML, crate files? It works fine for me so I'll need more context to recreate it.

Version 1.22 is up at ibrahimshaath.co.uk.

It includes a fix for a fairly serious batch crash (sorry about that one), improved behaviour for Serato libraries on secondary Mac volumes, and some UI bugs. Also, Mac localisations now obey the Language settings as opposed to Region.

If you have any problems, please raise them by email, and include as much detail as possible. I've had some very lazy bug reports recently and I just don't have time to chase them.

You're the man!

Version 1.23 is up at ibrahimshaath.co.uk.

It includes the option to filter batch jobs by file extension, which has been requested a few times. It also fixes a few tagging bugs.

Enjoy =)

Hello, i've got a problem, when i'm trying to analyse songs from serato but skip songs that have been analysed, keyfinder crashes and error message appears, help (v.1.23, mac)

I'm afraid I can't recreate the issue with so little detail; please send me an email with as much information as you can gather.

What does 100 bad packets mean? Like the file isn't all together there?

It means libav encountered problems decoding. It can mean some level of corruption in the file, but it more often means a badly (non-standard) encoded file or a DRM'd track.

Oh ok. Just wondering!

Just found your program.....works wonderfully! Fast and accurate. Well done! Now....I just have to find a new project for my BSc Comp Sci!

Sorry man! You could always go for tempo estimation... lots of interesting approaches to that.

...or a superior time stretching algorithm ;)

New version 1.24 is up at ibrahimshaath.co.uk

It fixes a tagging crash on WAV files, adds a load of tests for tagging so fewer issues should appear in future, and includes some new localisations.

Enjoy!

^ Thanks ^

:)

Thanks!

Thx Ibra, love your work!

I really love the program. Unfortunately the latest versions seem to have dropped the support for computers running Mac OS 10.6.8 Snow Leopard. Ist it possible to reenable that support? Or otherwise would it be possible to release an older version that doesn't do the update check everytime the program starts? That is kind of tiresome. ;-) Thank you in advance!

That's weird; my Snow Leopard machines work fine. I dropped support for 32-bit CPUs; is that the issue? Can you drop me a line and tell me a bit more about your machine and the messages you see at launch?

Yeah, I'm still on 10.6.8, and it's working perfectly fine for me. Though, I am on a 64bit chip.

Yes, that seems to be the reason. Sorry for the misleading. I use it on the first MacBook with a Core Duo processor. Would reenabling the 32bit support be a big deal?

Sorry about that, didn't think there were a lot of Core Duos still out there.
I'll give it a shot in the next release; it just makes building the supporting libraries etc a bit more tedious.

It appears to be two years since that first post up top, which means it's KeyFinder's second birthday! It's now been downloaded more than 20,000 times, which may not seem like that much to the big boys, but it kinda blows me away. Thanks so much to all of you for your support.

m best wishes for u! HBD!

Because you have made such a brilliantly effective product that is simple to use and helps us fellow DJ's to perfect our game.

What you did was offer something to the DJ community that others usually cash in on. For that, I salute you.

Many happy returns to KeyFinder.

congratulations on your anniversay... keep up the good work and many thanks

Oh, I'm sure if Ibrahim could cash in, he would be all about it. Y'all who love the software should be donating on his site. He deserves it!!

I hope Serato eventually integrates KeyFinder into SeratoDJ.

+1

Just sent in a birthday donation, I hope the other 20K downloaders do to!



Of course this is the best possible scenario... dare to dream

congratulations on your anniversay and thanx alot for what you are doing :-)
In my oppinion, the best program out there.
Keep up the good work and i hope this one day will be integrated in Serato.

+1.

Congrats and thanks for making and keeping this as a free tool!

Thanks for the kind words fellas. I will cash in a little bit if it's available (e.g. with MixVibes, and Serato if they so decide) but the free app is here to stay. =)

I've recently downloaded keyfinder and analyzed all my tracks, all the keys have come up nicely but they aren't showing up in my serato. any help?

Did you read the FAQ?

Spoiler: you did not.

LOL

WOW massively helpful, are you like Mother Theresa or someone? Now the sarcasm is out the way I've read the FAQ and sorted it out, loving your program as it really helps in creating a harmonic mix

Nah.. I think it was on spot, because you didn't


;)
