Indeed that's the behaviour I expect. Do I have to specify 16? I tested with lower numebrs (e.g. 4, 6)... Maybe that is the problem?Well, one midi port can always address 16 channels, and to avoid tinkering like "on which midi channel does instrument 5 has to play now so it will be heard on output 3" you better just use synth.audio-channels=16 ;)

fluidsynth -o audio.jack.multi=no -o synth.audio-channels=16 -o synth.audio- groups=16 "someSoundfont.sf2" you should get 16 stereo output channels. and since there 16 midi channels, each midi channel will get its own stereo channel. or which behaviour do you experience?
Well unfortunately I tested this and that's not the expected behavior.What that command achieves is indeed 16 stero pairs (l_00, r_00 etc.) but all channels are played on the first l_00 / r_00 pair plus there's 'something' coming out of l_01 / r_01 I am guessing it's maybe the reverb..
I opened a similar thread on LAU and someone provided interesting answers / pointers:
