I set mine up in "server mode" and use a file "synth.init" which contains
"loads" for all the soundfonts, select commands
and cc commands for "panning"
I start with:
fluidsynth -j -s -i -l -r 48000 -a jack -m alsa_seq -f /home/xxxx/synth.init
-o shell.port=9802 -o synth.gain=1.2 \
-o audio.jack.id=fluid2 &
inside another script.
At the end of that script I invoke another that does the aconnect(s) for the
USB midi input.
This was so long ago, I've forgotten which switch actually enables this
"remote automated" behavior.
