4.) Playing regular vinyl without having the computer atttached doesn't work.
Also playing regular vinyl when Scratch Live isn't opened doesn't work.
Of course I'm using the external power supply.

This is working well for me.
What input are you running a source into on the SL4?
You will not see the SL4 as a sound card device in other programs until you shut down SSL. When SSL is open the SL4 can only be used as its sound card.

This is normal. As soon as you shut down SSL you'll see it connect as a Core Audio device thus showing up in the SL4 Control Panel.
When SSL is open it cannot be used as a sound device for other programs or OS.

With your SL4 disconnected from your computer, do you see the green Thru buttons on on your SL4? What inputs on the SL4 are you running your turntables into?
What outputs of the SL4 are you running into your mixer and what inputs on your mixer are you running into?

Update:

SL4 works fine with Windows (Vista) and old MacBooks with OSX 10.5.x

We tested two different brandnew MacBook Pro 13" with OSX 10.6.7 today and having the problems that I described above. So it's three different 2011 MacBook Pros having the same issues with SL4.

It looks like it's a problem with new (Modell 2011) MacBook Pro and/or Mac OSX 10.6.7.

For anyone trying to reproduce the issues make sure you're using the latest model of MacBook Pro 13" with Snow Leopard OSX 10.6.7.

Do you mean all of the issues only appear when using the new MBPs?

Ok.. I tested with my brand new Quad Core i7 running 10.6.7.

I did get a Kernel Panic during my testing when I was simply unplugging and replugging the rca into the various inputs while testing Live Feed.

It was working as expected prior to the Kernel Panic.
Once it Kernel Panicked I had to unplug the usb and power cable from the SL4 before I could get Live Feed to work again.

So.. I'm going to guess you could fix your issue by cycling the power on your SL4.
Unplug both the usb and power adapter, plug it back in, and then open SSL.

That should get Live Feed to work.
I'm thinking this was also the reason for regular audio not being able to pass through your unit.

Let me know how you get along.

Somebody else in the German forums told me it's because the new Macs are 64bit and Serato only supports 32bit.

Will have another look at it later, but 32bit would suck big time.

And why is that?

Do you know the difference of a 32Bit and 64Bit OS?

Serato is a 32 bit program but it still works when using a 64bit OS.

Yes, it works for basic deejaying but not all features like I allready said.

I'm going to test 32bit mode now.

I've tested what you think isn't working and it is working.
I didn't have to boot up in 32bit mode. You don't have to when using an SL4.

At this point I would suggest calling us when your in front of your setup so we can do some troubleshooting over the phone.
--> serato.com

Just checked 32bit mode and then I'm able to use the SL4 for any other application, as long as Scratch Live is closed.

When deejaying in 32bit mode I'm still unable to get any input signal for the Live Feed feature.

Like I said, it doesn't matter if your using 32 or 64 bit.

SSL will never show up as being connected in the Control Pane when SSL is open.
Nor will you be able to use it inside of any other program while SSL is open.
This is by design and not a bug.

As for Live Feed not working.. as I said, call me when your in front of your setup and we'll do some troubleshooting over the phone:)

nice that it works this way!

however, this still isn't normal behaviour.

Zach, do you have any solution/explanation for this?
AFAIK other users with 2011 MBPs don't have that problem.

but maybe those other users coincidentally all have beta access -> newer drivers on their machines? (this is just a guess, i have no insight on this)

i can't try since i don't have a 2011 MBP.

is there a way to completely remove the driver before re-installing it?

We tried three different brand new 2011 MacBook pros (Modell March 2011) and had the same issues. So it might be the box or Apple.

I will give my own MacBook to the local Apple Store tomorrow and let them do all hardwaretests they can and really hope it's not broken since it's only a few weeks old.

You guys.. there is nothing wrong with the SL4 and its current driver lol!


This is exactly how it works when using it on the 64bit side.

BBN... call me. This should be an extremely easy fix.

I cant help but you laugh reallllllllly hard

I'm also laughing, but only if I'm not using SL4 and Scratch Live ;)

Still crazy that it's three different Macs having problems with the SL4.
Mine is at the shop for some insight testing now, but everything else than SL4 and Scratchlive is working without problems. I really hope it's the box, so I'll be able to send it back and get a new one in exchange.

BBN i doubt it is the box.
as i said i can not test your scenario.
but i think you should completely remove the drivers and reinstall since it works fpr other persons in 64 bit mode.

plus if i understand you correct it works in 32 bit mode for you. so it can not be the hardware.

Even in 32bit mode I can't get any signal into the Aux-In.
We connected another computer, MP3player and the headphone out of my MacBook to the Aux-In and played some music. Then loaded the Aux-In Live Feed track to a deck and didn't hear anything.

Can't do anything at the moment, because they need a fes days for my MacBook to be checked at Apple, but would be nice to know the names and locations of the drivers on a Mac. So before I'm sending back the SL4 this could be my last testing and possible fix of the problems.

did you see the waveform building up on the deck?
or just a growing "silence line"?

No waveform, deck doesn't even rotate.
Chanels 1 - 4 built a waveform and the decks rotate so I'm able to scratch and loop the recorded signal. Aux-In is silence.

I see your issue with using Aux with Live Feed.
I'm not sure why this is even an option in the software. I don't think this should even be there.
The reason why is there is no virtual deck to show you what is coming in on the Aux input.
For example.. you can choose Live Feed usb channel 1 by selecting usb channel 1 on whatever deck your using and dragging/dropping the Live Feed usb channel 1 track onto the deck.
There is no Aux assignment in the usb section for a virtual deck. You can only choose 1-4.

So... don't use the Aux for Live Feed as its obviously not intended to be used in that way. As I said, as far as I can tell you shouldn't even see the Aux Live Feed as an option.
With that said, use one of the other 4 inputs.

you DO need the record option on the aux in to record your mix with the SL-4
that is what its intended for.
so i guess this is why it appears as a live feed option, even though it is not supported, since all inputs appear as live feed options

Correct.. use Aux for recording your set.
Use 1-4 for Live Feed.

So we're getting nearer and nearer to having everything fixed.
But somehow I still don't believe 64bit mode works on new (early 2011) MacBooks, after reading a lot of forums and watching videos from guys like the SeratoTutor (Konix) who amongst many others says we have to use 32bit mode.

What isn't working when in 64bit mode with your SL4?

Everything I've been posting on top.

This forum needs an edit function ;)

SL4 control panel says "SL4 not connected" even when Scratch Live is shut down in 64bit mode. Playing regular vinyl isn't possible and of course, because the drivers think SL4 is not attached, it's also not possible to use the SL4 in any other application as a soudcard.

All this only happens in 64bit mode on three different new MacBook Pros (build early 2011, the newest models you can buy).

32bit works perfect, except Live-Feed is loosing the audiosignal a lot, when I start scratching or let a loop of the recorded signal play.

Ok.. I got it..

I was not thinking there was an issue with the SL4 when using it on a 64bit OS.
You are correct though. It is not seen as a sound card outside of SSL or inside of other programs when booted in 64bit.
Lamo!

I'm hoping the updated drivers will be available to the public prior to the 2.3 version comes out.
No promises but I'll work on that:)
