[LAU] Fluidsynth: map each channel to individual jack audio output

Hi all,

I have also posted this on the fluid-dev list, but maybe there is some 
wisdom on LAU about it as well :)

What is the current status of synth.audio-channels and 
synth.audio-groups on Linux with jack?

By starting fluidsynth with something like:

fluidsynth -a jack -o synth.audio-channels=4 -o synth.audio-groups=4 \
-o audio.jack.multi=no

I do get 4 pairs of jack audio outputs.

However the behaviour isn't as expected at least according to this (very 
old post):


Ideally is there a way to have each channel routed to a separate audio 
output on jack these days? Any help appreciated.
