  Don't think it should make too much difference, assuming the code is thread 
sensitive.

  I'm doing things the second way, because I want the left hand of my keyboard 
to
  produce one .wav stream, and the right another.
  BTW, does your FA-66 look like multiple MIDI inputs to qjackctl?

  I had to make some mods to qsynth to have it route even/odd MIDI input
  channels to different synth engines (plus some other options).
  Unfortunately, my GUI/C++ acumen is zilch, so the mods depend on hacks
  to qsynth's rc file handling.  But it does work, so I can record 3 separate
  file streams (vocals, left, right) at the same time.
