Yes. But I advice you to use QSynth [1] to do this, it has a checkbox
labelled "Multiple Jack Outputs" in the audio tab allowing you to enable this
feature. The settings "audio channels" and "audio groups" are used to map the
MIDI channels into jack outputs.
If you want to do this with the FluidSynth command line interface, then you
would need some options at startup, for instance:
$ fluidsynth -a jack -r 48000 -o audio.jack.multi=yes \
-o synth.audio-channels=16 \
-o synth.audio-groups=16 \
SoundFont.sf2
The above sample should map every MIDI channel into a different jack output,
but I warn you that it didn't work for me, so it can be broken or needs some
other option that I can't remember.
