I Got it!

I haven't tested everything out to see if all is running properly but I i got Serato to detect my NS7!

I d-loaded and installed the latest drivers again and installed. Win7 took the drivers and the NS7 at the USB showed installed but Serato still would not detect the NS7.

I went into the MIDI device and still showed code 28 (driver not installed)
I attempted to reinstall and the updater said it the driver file did not exist and could not locate it.
I d-loaded the driver again, located the file that Win7 said wasn't there and copied the location of the driver file, went back into the MIDI driver updater and manually entered the location of the NS7 driver and.... it worked!

I am now connected! I will now spend the weekend testing out performance....
Thank goodness!

Hey DJCru,

I'm glad to hear you got it working! How did your testing on the weekend go?

hey sorry for taking so long to reply but i been setting up laptop for past week.

things have been good for the most part but I am noticing intermittent CPU spikes which actually cause the music to skip and even stop!

i would like to see it happen again to confirm but i beleive the platter even stopped with the music. I touched nothing and after 7-10 seconds of nothing it started again.

I am not running any other progs so priority should be to ITCH.
not feeling to good about this at all....

so i have seen this happen 3 more times since my post as I have had my ITCH with the NS7 on continuous play all evening.
the platter continues to spin but the audio completely hangs for 5-10 seconds.

I see in the upper right corner that the MIDI indicator comes up full red. I am running no other progs and the file is a good file ripped from the CD. i have fixed or deleted all corrupt files in ITCH.

what would cause this to happen????

Hey DJCru,

If the MIDI indicator light is coming on then this means you are getting USB dropouts. The first thing I'd suggest is try all the suggestions in the following articles:

www.serato.com (click link)

www.serato.com

Next, can you please go to the Hardware tab on the ITCH Setup screen and try increasing the USB buffer size.

If you find that you are still having these dropouts after all this, please follow the steps in the following article and to run a DPC trace report:

www.serato.com

Once you have a report, please attach it to this thread.

Thanks.

Hi Michael,
sorry for being impatient on my other thread, just so frustrated right now. Please know that our thoughts here are with your fellow New Zealander's in Christchruch. I hope that none of your friends or family were affected.

I tested my HP w/Vista-32 with ITCH/NS7FX for 36 hours. I had synced both decks and walked away. After 36 hours they were only out of sync by <1/8 second. In other words, it ran flawless!
user ENFA mentioned a similar issue to me with a new laptop running 7-64 and solved it with a fresh install. I opted to perform a fresh install. interestingly enough the recovery process exposed a potential HDD error. Future Shop is installing a new HDD today and performing a fresh Win7-64 install.
I will be back to testing ITCH/NS7 on this hopefully by tonight. If the issues continue I will perform the DPC trace.

Thanks everyone for your help! I will keep you all posted on my progress...

Chris........

No worries, I know how frustrating this can be. Hopefully the fresh install helps, if it doesn't then a DPC trace report will be very helpful to trying to find what is causing this.

Yeah it's pretty bad in Christchurch at the moment. New Zealand is pretty small so when something like this happens it really effects everyone. Thanks for your kind thoughts.

okay...
I got my Toshiba i5 win7-64 back from Future shop with a new HDD and fresh install of Win7-64.
Future shop removed all trial software. I applied all Windows updates and Toshiba mfr. updates including BIOS update. THEN I ran a scan disk and a defrag before installing ITCH 1.7.1 and before copying my library to my new HDD.
My ITCH 1.7.1 installation was quick and painless and I had no driver issues as I had before. Device manager showed the 2.9.13 drivers installed from right from the ITCH software. (thumbs up!)
This is everything I did. I have not networked my comp nor been online. I have not installed a virus scanner nor any other programs or drivers or performed any OS tweaks. I left Windows7-64 and ITCH 1.7.1 with all installed default settings.

I scanned my library, loaded both decks on continuous and let it run. Sadly, within a few minutes I saw and heard a USB drop for about 2-3 seconds.
An hour later I saw the platters had stopped turning and both decks were hanging - essentially paused(?) I tapped CUE/PLAY on each deck and the songs continued.
I reloaded the decks and let ITCH/NS7 run over night. (both with same song and synced manually)
This morning I woke to see the platters were turning but no music. Both decks were on the same song at beat grid 4,283 and counting - the songs had long ended but ITCH continued on and on without going to the next track. There was also no audio pointer and I could not pause or stop the "songs". (NOTE: I had seen this b4 new HDD and with other mp3's- no corrupt icons on any files in library)
I attempted to reload new files into both decks but no waveform or audio pointer appeared. I restarted ITCH (left NS7 as is) and loaded to new song files and still no waveform or audio pointer.
I then powered down NS7 (left ITCH alone) and the moment it powered down (confirmed by Windows audio clip for USB disconnect) the one deck waveform loaded and the audio pointer appeared.
I powered up NS7 and the other deck loaded with waveform and audio pointer. I pressed play on both decks and all was fine.

so here we go again. I will run a DPC trace report tonight. I need to resolve these USB drop outs. I have not had USB drops with my other laptop (Vista32 Duo Core) just my i5 Qosmio before & after new HDD and fresh Win7-64 install and ONLY with ITCH.
CUE 7 ran both my NS7 and DMC2 overnight with no USB drops.
(*sigh* 4 weeks at this now...)

my complete comp specs here:
209.167.114.38

Toshiba Qosmio F60, Intel® Core™ i5-450M Processor (2.40 GHz, L3 Cache 3MB) with Enhanced Intel® SpeedStep® Technology
Memory: (Slot 1 X 4GB) + (Slot 2 X 2GB) DDR3, 1066MHz
Display: Type: 16:9 TFT Active Matrix colour LCD display
Video: NVIDIA® GeForce™ GT 330M Graphic
Video RAM: 1GB GDDR5 discrete graphics memory
Sound Card: Realtek ALC272-GR High Definition Audio Software Sound
Hard Drive: 640GB, 5400RPM (S-ATA)

Windows 7 - 64

Note: one file loaded when I powered down as ITCH went into the offline player mode. When I powered up NS7 the second file loaded as it switched back to online with dual decks

ok DPC report sent.

above are screen prints of various settings for your review also. I am just gonna throw everything at you and you tell me if you see anything!

the sooner the better.
thanks,,,,

more on my system.
I have further tweaked the OS. I have disabled all networking & wireless. No Virus scanner. No Windows Defender. Indexing is off. USB Buffer at 1024, platter at 33, hi-fi resampler unchecked. all power options are full boar - no sleep, no turning off HDD, no screen saver, 100% max frequency, PCI power management is off, etc. etc.

I have had my system running for a couple hours now and while the drops seem to be smaller and less frequent I am still getting USB drops. 1 - 2 seconds (???!!!) (at least better than 3 - 5)

Micheal R - tell me why my CPU indicator in ITCH lights up red when...:
- task manager shows ITCH CPU load at less than 10%
- Resource Monitor shows CPU usage at 20 - 30% while at 66-76% max frequency
- HT cores 1 & 3 are parked

How is this a CPU peak indication? My system idle is at 92% with ITCH running. My system is practically asleep! WTF? I will upload a screen shot of all 3 windows showing resource mon, task manager & serato CPU indicator lit so you can see for yourself

I have been on this forum for a month and I still have USB drop outs. I am calling Numark rep tomorrow. I am giving this one more week or i am returning my NS7FX and staying with my old DMC2 with VDJ Cue7.
I guess I bought a new (more powerful) laptop for nothing since my old laptop is plenty for VDJ.

let ns7 run all night. woke up to see both platters stopped. Both decks songs stopped mid way for no reason.
pressed cue/play on each deck (which set a temp cue point) then pressed again and songs continued as if nothing happened.
this is what happens with more sever USB drops. thus they continue....

i have installed ITCH 1.5 and have 2.9.13 USB drivers for x64 install (although 2.9.3 seemed to work fine)
I have my USB buffer at 1 (fully to left) and hi-fi resampler checked. Deck at 33
I have fx loaded on both decks which are running matched to the same song on continuous.
I am intentially scratching the hell out of the decks to attempt a USB drop.
I am crossing my fingers but no USB drops yet and I am running at 1 on USB Buffer.
In fact, my CPU indicator or MIDI has never flashed for even a nano second. I say again, at 1 on my USB Buffer.
I gonna let this run while I sleep and see if decks are still running in morning. (Changing deck to 45 RPM now)

okay here is my update....
I upgraded (yes UPGRADED) to 1.5 last night and I am running 1000% better(2.9.13 USB drivers). i am running at 1 on my USB buffer, 45RPM and have fx on both decks & am scratching the hell out of them both while reloading tracks over and over. I even did a virus scan on a USB stick while doing this without a glitch. My system also ran all night for the first time without stopping on its own. Never accomplished this with 1.7.1
I did have 2 drops within about 10 minutes of plugging in the USB stick and activating my virus scanner so i have since removed the USB and shut off VS and havent had any drops since. (about 45 minutes now)
My MIDI light came on during the drops but CPU has never blinked once during anything I have thrown at it - with USB buffer at 1 (!) - in 1.7.1 I couldn't get down to 256 (i think 3rd setting?) without a steady red CPU light

I EVEN UNPLUGGED the USB for my NS7 by accident and ITCH carried on playing internally - I then plugged it back in a few seconds later and the music came back on right where it should have been without missing a beat. Not even a stutter! just connection and music.
Bottom line... I am sticking with 1.5
I will wait until 1.7.1 issues are fixed before ever DJing with it. I will keep all posted here. I am still unsatisfied with these performance issues but 1.7.1 is not ready for x64 (at least for PC) so this should listed as NOT compatible for 1.7.1

At least now i am comfortable enough to DJ live with my NS7FX. I will have my DNs700 loaded with an emergency track list though! ;)

Cheers

serato... any comments on my DPC trace reports?

upadate with ns7fx with ITCH 1.5
i discovered Nvidia released new drivers for my laptop only a few weeks ago and newer than on laptop mfr website so I installed these. not sure if these helped with serato but i ran itch 1.5 all night in fact for 18 hours without music and platters stopping. never got farther than 2 hours with 1.7.1
today i took if further....
So here's a test I just performed:
- I set USB to 1
- 45RPM
- HIFI checked
- loaded and playing both decks both with fx active
- virus scanner on
- external hard drive plugged into 3rd USB port

I am playing on both decks while transferring GB's of files over USB from ext HDD to my comp, ALSO i am defragging both my comp AND my ext HDD AND I am running a VIRUS SCAN on my Ext HDD while scratching the hell out of both decks, loading tunes in rapid succession, fast forwarding/rewinding looping etc. ALL AT THE SAME TIME with only one tiny stutter after 20 minutes of this torture. CPU light has not lit once.
I gotta say that right now i will stay with 1.5
cheers....

Your nvlddmkm.sys module is causing massive latency issues, I am assuming this is the cause for these dropouts.

www.file.net

This link suggests to disable this, but since it may be your videocard driver, this may mess things up. I'd first see about a video card driver update.

I've just done a quick look on Google for this, and see there are many issues with this module, I'm assuming these are being looked at or have been looked at so there will probably be a solution somewhere for this latency. Let us know your findings. I'd normally have a solid suggestion here about what to do, but this may require it may take a bit of trial and error unfortunately.

Hi Matt-C
thanks for reviewing my DPC Traces. since I performed these traces I discovered that Nvidia released even newer drivers than mfr. website had posted. The Nvidia Audio and video drivers I installed last night were just released end of january. I also reinstalled NS7 firmware and calibrated.
I am running a DPC trace now and will attach.
I have ITCH 1.7.1 at USB 1 and 45 RPM both decks playing with fx but OS tweaked with no Virus scanner and networks disabled. I also running a full bore DJ Power scheme. I am running 1.7.1 like this as this is how i ran 1.5 earlier with no usb drops.(see above post where i tested 1.5)

I seem to have drastically reduced the USB drops but why does 1.7.1 just "stop" after about 2 hours on continuous play? I am never around when it happens but i count the number of tracks played and it's always about 2 hours in that it hangs. I only need to press play/pause 2 times and the song carries on like nothing happened. This does not happen with 1.5 - i ran all weekend 2 tests for 18 hours each on 1.5 and neither deck ever stopped.
Above i posted about how hard I tested 1.5 without drop outs, how can the performance requirements between 1.5 and 1.7.1 be that far apart?
I will look into what I can do about my nvlddmkm.sys module.
thanks again for input.

Can you please make sure that you have analyzed all your files in the offline player (hardware is disconnected). Simply press the Analyze Files button and wait until this has finished (If it crashes let me know).

Then in the ALL... tab, click the top empty box of the first column (on the same row as Artist and Track are displayed). This will group all similar library entries together.

If you see any tracks with a lightening bolt through them, you will need to remove these from your computer - these files are corrupt. Simply highlight these and press CTRL+DELETE.

You will need to either re-download, re-rip, or convert these files and then import the new versions as these original files are corrupt. I would recommend that you try to get rid of these files completely from your computer.

Let me know if this helps.

As for your report there are these that are showing up as causing latency now (though less latency):

nvlddmkm.sys

Still causing issues, though less. I am wondering if this will be fixed by doing the next adjustment...

USBPORT.SYS

* Disconnect all other USB devices until you are working (then add them one at a time in case another device is causing latency).
* Use a different USB cable.
* Go to your computer manufacturer's website and check if there you are using the most up-to-date drivers.
* Try using an external power supply for your hardware.
* Try connecting to a different USB port.

FYI... 1.7.1 "stopped" again today after 2 hours - thus before and after the installation of the most recent Nvidia audio & video drivers

i will do some more homework on this.

All of my files are analyzed and i have no corrupt files. This was the first thing i eliminated when i installed ITCH

USBPORT.SYS
- i have no other USB devices running only NS7 & FX
- NS7 has it's own power supply
- I have tried multiple cables with no noticeable variance in performance
- I have tried all ports in multiple scenarios with no change to performance.

any comment regarding why 1.5 is performing light years beyond 1.7.1 as far as stability goes? Why I can push my PC to the EXTREME and load 1.5 for BEST performance and not have USB drops but no matter how much i "dumb down" 1.7.1 I get drops and stops? just curious about your thoughts on that...
thanks

OMG!!!!!!!
OMG!!!!!!!
OMG!!!!!!!
OMG!!!!!!!

I CANNOT BELIEVE WHAT I HAVE DISCOVERED TONIGHT!!!

Thanks to Matt-C reviewing my DPC trace and telling me about Nvidia nvlddmkm.sys I have made a HUGE leap forward. Nvidia powermizer!

I found a forum talking about the Nvidia Powermizer and after much research found this:
blog.paulgeorge.co.uk
which had a link to Nvidia power switch found here: www.box.net
this allows you to turn off Nvidia powermizer (which recent Nvidia drivers do simply allow you to do!) I also went into the NVidia control panel and in advanced global settings i selected under "power management mode" prefer maximum performance.

The concept of all of this is counter intuitive (at least to me it was) but I found a blog on the Nvidia forum (sorry can't find the link right now) where a guy discovered that his DPC latency actually went down (improved) when he taxed his GPU (ie: watched a movie). and thus he fixed his USB drop outs by always having a movie running.
I couldn't believe this so I downloaded DPC Latency Checker V1.2.0 which lets you view the DPC latency in real time. I was seeing that my DPC Latency was not changing with or without ITCH running. AND 1.5 vs 1.7.1 was no difference in latency(??) i was averaging between 250us - 1200us
I was seeing above 1000 (yellow) about 40% of the time.
THEN as I was watching this in real time with ITCH 1.7.1 running I put on WMP and WATCHED A MOVIE.
This blew me away! My latency went DOWN (improved) WAY DOWN! I went from being above 1000us 40% of the time to rarely going above 500us. My latency improved 100% by watching a video!
HOW?? Nvidia powermizer adjusts the GPU up/down depending on demand. The interesting thing is it's not the clocking up that causes DPC spikes, its the clocking down. Thus by taxing the GPU the DPC latency improved 100%.
I then installed the Nvidia powermizer switch which allowed me to simply turn off powermizer (something I could not do in NVidia control panel) and VOILA!
My DPC latency now averages about 400us and maxes around 900us but rarely gets there.
I cant say yet that this has solved all my problems but in past 2 hours I have had zero USB drop outs with 1.7.1
I am even seeing in DPC Latency checker that my latency actually stabilizes and stays low (good) when ITCH is running vs when its not. very interesting phenomenon.
Matt-C , i will attach a new DPC trace report with 1.7.1 with Nvidia powermizer off. Let me know how it looks now and if there is any other issues you see.
thanks for your help!
Cru

BTW - ITCH 1.7.1 in this DPC trace is running at USB - 1, 45RPM with hi-fi checked and screen refresh at 60. Both decks running.

unbelievable....

of all the tweaks I've done the best thing yet to keep my DPC latency down is to loop a video in wmp while I am Dj'ing.

Nvidia execution time has gone from 1.3 to 0.17
I am running ITCH 1.7.1 with USB -1 and 45 RPM. DPC is averaging about 300usec
what a waste of a month....

i will try this, thanks man

good luck! and let me know if it helps.

you can download latency checker here:
www.thesycon.de

my latency is all on green 500us, the Nvidia Powermizer did not work i still get dropouts i think i need to change laptop

Hey Raspopo,
I am certainly not a tech nor a Serato expert by any means but I don't think 500usec is all that bad. remember that is the sum of all your DPC's of which ITCH is just one.
I have found that powerswitch does help but I still play a video in WMP while running ITCH and I see a further reduction and/or stabilizing.
HOWEVER, I still see major DPC spikes (one every couple hours) on occasion which I am not able to identify as of yet (ie: don't know if ITCH/NS7 is the source or not). having said that I still don't get the drop outs in 1.5 that I do in 1.7
FYI - I also disabled ACPI compliant battery in Device manager as this module kept coming up as one of the higher DPC execution times. The battery still works but you don't get the battery meter in your system tray. The performance pay off for this is worth it to me...

0k thanks again i will try that and be back ti u

update.
intel released new chipset drivers 4 days ago and i installed last night. i have also super tweaked my system to an insane degree.
i have disabled all networking (show hidden devices in dev manager and there are a dozen more things you can disable in networking)
disabled graphics card and sound card
disabled ACPI
in services i shut of numerous unnecessary items - too many to list here but so many pertaining to networking - like network location awareness, workstation, computer browser, etc.
disabled some intel power management features
etc etc

i have viewed the windows event viewer and found ID63 adobe air error coming up several times so i installed latest version in hopes to resolve this.

I have my comp running for 10 hours without a single dpc spike above 1100usec. i have never achieved this before. I alaways saw a spike about once per hour of around 7100usec but could not isolate it. whatever it was I must have shut it down or intel drivers fixed it.
i have now run ITCH (internal) for about 2 hours with no dpc spikes (not listening for audio cause not at home - just analyzing dpc) highest spike was 1799 usec but only ocurred once and that shouldn't cause a drop out.
i will test at home on NS7 then start turning things back on to see if they return so I can pinpoint the random 7100usec spike culprit!

Cheers...
