Aggregate device sync problems
Ok, this could be a couple of things...
I have a G4 Quicksilver upgraded to dual 1.4GHz, Audiophile 2496 soundcard and system outputs combined in an aggregate device to give me 2x stereo outs - one pair goes to a stereo channel on my sound desk and carries all but my kick drum, the other output into a mono pair panned L-R carries the kick. The reason for this is to sidechain the main mix with the kick (yes, I produce Hard House...)
Problem is, after a wee while the kick goes out of sync with the rest of the mix. I put it down initially to differing EQ settings in my desk. Nope. Then perhaps resistance fluctuations caused by heating up of the circuit. Nope, because occassionally it comes back into sync, so I could rule out hardware issues. Another issue is every now and then Logic will drop the connection from my MIDI controller to Reason via ReWire2, and will only work when playing, not when stopped. All other MIDI notes routed to Reason work fine. When viewing Reason it looks to have jammed, but will work fine when I press play again. Again, this appears to be an intermittent fault, which leads me to think both issues are driver or software based.
I am required to have System Prefs/Sound open all the time I am working to prevent stuttering when pressing stop as a work-a-round to a previous problem with the Delta series soundcards.
Has anyone else experienced any of these weird issues, and know of any work-a-round?
