However the behaviour isn't as expected at least according to this (very old post): https://lists.nongnu.org/archive/html/fluid-dev/2004-02/msg00027.html Ideally is there a way to have each channel routed to a separate audio output on jack these days? Any help appreciated.'-o synth.audio-groups=4' fails: `fluid_settings_getint' returns 1 after `process_o_cmd_line_option' (also tested with a printf). sh> fluidsynth -a jack -o synth.audio-groups=4 <<< settings 2>/dev/null \ | grep audio-groups synth.audio-groups 1 Idem with "-o synth.audio-channels=4 -o synth.audio-groups=4", but "-G 4" works: sh> fluidsynth -a jack -G 4 <<< settings 2>/dev/null | grep audio-groups synth.audio-groups 4 There is a comment in `src/fluidsynth.c:594': /* The 'groups' setting is only relevant for LADSPA operation * If not given, set number groups to number of audio channels, because * they are the same (there is nothing between synth output and 'sound card') */ tested with: sh> fluidsynth -a jack -L 4 <<< settings 2>/dev/null | grep audio-groups synth.audio-groups 4 The follow example works (audio.jack.multi=no by default): sh> fluidsynth -a jack -L 4 load /usr/share/sounds/sf2/FluidR3_GM.sf2 select 0 1 0 0 select 1 1 0 20 select 2 1 0 30 select 3 1 0 40
Thanks for testing... However I'm not really sure what to make out of that apart from assuming that the use case isn't directly covered by fluidsynth?
I imagine the easiest workaround would be starting multiple fluidsynth instances, maybe lowering poliphony (not sure what impact this has on resource consumption), possibly scripting it...
