ahh. yes, that's familiar.  I've had that problem before, about 2  
years ago, using an RME Fireface 400 with a Powerbook G4 on OSX 10.4  
for multichannel performance.  quite nasty.

I think I recall that it came down to Portaudio, so I think I fixed  
the problem by using the Jack interface.
But I'm not 100% sure of that.

try jack and see if that fixes it.

anyone else know a fix?
