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 ...
