M-Audio NRV10 Problems w/ v10.5.2

Same problem here too.
But at least you've provided me a solution.
I DO know it's not the NRV, cause I've checked with another DAW on an XP system and it worked fine, so it seems like something with the NRV driver on the MAC.

Please post an update in case you find a better solution.
Thanks,
Spark.

Hi All,
Can someone please help with a problem I'm having w/ my new M-Audio NRV10 & iMac v10.5.2? First, I did download beta NRV10 drivers....

Problem:
When I select (as instructed by NRV10 manual) GarageBand> Preference> Audio Output to: NRV10 9/10 & Input to NRV10 Mutichannel...I get pops and clicks (sounds like feedback) on all tracks recorded into GarageBand...when I change Output only to Built-In...the problem disappears...

It could be a simple set-up issue or the driver (beta)...any suggestions would be appreciated!

Based on your workaround, it does sound like a driver issue.

However, one thing to keep in mind is that while the NRV-10 may want to see the stereo output on channels 9/10, I believe that Garageband will only output its stereo out on channels 1/2. The drawback is that accommodating GB's appetite for channels 1/2 will cannibalize the first 2 channels on the NRV-10 for GB playback, but I'm not sure if there's a way around it.

On the other hand, if you are trying to circumvent GB's insistence on outputting on channels 1/2, perhaps that is causing the problem.

OK, I think I've figured it out too (I'm not sure I can fully explain WHY it happens tho):

The problem occures when you select ANY stero pair (not only 9/10) as Audio Output in GB preferences. Actually the only thing that should be defined there, both on Audio Input AND Output is "NRV 10 Multichannel".
"So how do I route playback stuff to either 'FW 9/10 to Phones' or 'FW 9/10 to CTRL Room'?" you may be asking.
Well, with Advanced DAW software it should be done by individually selecting channels 9/10 as output for each corresponding track, alas GB has no individuall control for track output. only Input Source. The default output channels on GB (while at "Multichannel" mode) are 1 and 2.

This means that untill GB features track output channel control you are either forced to sacrify channels 1/2 OR use another DAW.

Your explanation makes sense. It's really a philosophical difference:

GB sees 1&2 as the default playback channels; the NRV10 sees 9&10. The result of this heroic battle between competing musical titans is... GB wins, forcing the NRV10 to give up Channels 1&2 in defeat.

Sure, it would be nice if you could specify output tracks, but I think this is one of those features that GB limits on purpose in order to keep things simple at the expense of flexibility-complexity.

Right.
And BTW, if you've never heard of it yet and would like to try a very cool and professional and a real "rising star" DAW software, you should check out Reaper.
They are working right now on a port to OS X and there's already a "preview" version that is actually working (well, most features. at least the important ones :-)).

I think Reaper is a cool project, but it's not really what GarageBand is about. It's kind of the opposite approach. Also, I don't think Reaper is ready for prime time on a Mac yet. However, I too admire the way they're developing it.
