Sry, misunderstanding. This fix I was describing only fixes the
opposite behavior of the audio.jack.multi option. It doesn't fix the
issue of this discussion.

audio.jack.multi defaults to false. Starting fluidsynth with multiple
outputs and WITHOUT explicitly setting audio.jack.multi to "yes"
shouldn't work according to its documentation. However, it does work,
and fluidsynth creates as many outputs as requested. But doing the
same thing again this time setting audio.jack.multi to yes will always
only create two channels: "left" and "right" (due to the wrong boolean
decision described previously)
If necessary, I'll create a ticket for this minor issue.

To summarize the main issue:
case 1: audio.jack.multi=yes using N outputs, while N>1
Two (mono-)channels are created. Only voices mapped to output 0
(according to Midi_Channel_number MOD N) are hearable. Reverb of those
voices is also hearable. Additionally you hear soft reverb from some
other midi channels (hard to say from which ones).
case 2: audio.jack.multi=no using N outputs, while N>1
N stereo outputs are created. Voices are mapped to their belonging
output (Midi_Channel_number MOD N = output). NO reverb hearable at
case 3: audio.jack.multi=yes using 1 output
Two (mono-)channels are created. All Voices mapped to that single
output. Reverb works like a charm.
case 4: audio.jack.multi=no using 1 output
Same as case 3.
Note that I was talking about the unmodified code, i.e. with the
inverse audio.jack.multi option.
Regarding the main issue of this discussion, I would create a bug
ticket. Do you agree?
