Hello,

I have been experiencing an issue for MONTHS, trying to find a solution, and in my spare time I try to research the issue.  I just found this thread, and I have a suspicion (although I hope I'm wrong) that my beloved Fireface 800 might be the cause of my problem:

I am a composer and run Logic 8.0.2 on an 8-core Mac Pro loaded with RAM.  As you all know, we still live in a 32-bit world, which limits us to less than 4 GB per app.  So, in addition to my VI slave machines, I have been trying to run some VI's in standalone mode on my main machine.  Great concept, huh?  Should be easy - set up some IAC ports for inter-app MIDI and use Totalmix loopback to get the standalone apps' audio back into Logic.

Well, it has never really worked.  I've figured out how to get just one standalone VI going in addition to Logic (NI Kontakt 3).  However, I have to do all kinds of voodoo to even get that far.  When I do get it running, it all falls apart as soon as I launch another VI app, and I think I've finally found the problem: the Fireface is not really a multi-client interface, at least from what I gather here...  If I should be able to do the following, then I stand corrected:

Boot Mac
launch Kontakt 3; each channel output is set to an ADAT pair (those outs are looped back in Totalmix, to feed Logic's mixer)
launch Logic 8.0.2 - so far, so good (Logic's mixer has 24 live inputs enabled: 8 analog & 16 ADAT from Fireface)
launch EW Play (StormDrum2) - Kontakt 3 no longer generates audio.

Is this because Play and Kontakt both use the same ADAT outputs?  I've tried isolating them so there's no channel sharing, but one still cuts the other off.  Or is this because NI stuff hogs even unassigned outputs in the background as some have suggested?  Incidentally, IAC is disabled - all MIDI is done with physical cables to eliminate that variable...

Either way, it's very frustrating as I can't do what I should be able to do.  Hope someone can shed some light on it!

Thanks so much,

Jim

Thanks, Matthias.  I know there's no ASIO on Macs - I was using the term "multiclient" conceptually.   I didn't know Core Audio handled those aspects - maybe I posted in the wrong thread ;-)

I posted here because earlier in the thread I noticed some posts where people weren't having this issue while using other interfaces.  However, it could very likely be an issue with Native Instruments' output handling (wouldn't surprise me).  I would certainly give the benefit of the doubt to RME based on my 4 years of raving success with my Fireface ;-)

Thanks again,

Jim

It sure feels that way at the moment.  NI in particular is notorious for having the "it's not our problem" attitude, but the more I research, the more the problem doesn't seem to be exclusive to them.  I have some other audio interfaces around - when I get a chance, I'll see if the problem occurs with those.  I do know that if I just use the Mac's internal audio hardware, the problem goes away - I can use standalone apps all day long outside of Logic.  That doesn't help me though - I want to route everything back into Logic, and Totalmix is perfect for that!

Oh, and where's the link you were referring to that MC posted?  Is it for Mac users or Windows?  If there's a solution to this, I'd LOVE to see it!

Thanks so much,

Jim

Old thread but I've got a quick question: I'm trying to assign Kontakt 3 to a different output than 1+2. It seems Kontakt selects outputs 1+2 with no way to change it as in the Kontakt settings you simply select 'Asio' and 'FireFace Asio'. I want to use the multi-client option but I'm not sure Kontakt offers a thing where you can select which channels you want them to output on. Am I right on that?
