As a data point, I ran two different sa.c files (the audio engines sfront produces) set up as softsynths using different patches under OS X (using CoreAudio + CoreMIDI, not the AudioUnits API), and it worked -- two patches doubling together, both looking at the same MIDI stream from my keyboard, both creating different audio outputs into CoreAudio that were mixed together by the HAL. So, for N=2 at least, OS X seems to handle N low-latency softsynth apps in different processes OK ... ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro -------------------------------------------------------------------------
