That's why I mapped the 3 stereo-outputs via jack to my single stereo
soundcard. I heard all voices, except for the reverb.

So to avoid a wrong soundcard-driver-configuration I started jack in
dummy mode with 6 capturing and 6 playback channels:
jackd -r -d dummy -C 6 -P 6
followed by starting fluidsynth:
fluidsynth -a jack -L 3 my.sf2
and then capturing the output of fluidsynth. All midi channels were
clearly hearable, again, reverb was missing.
Restarting fluidsynth changing -L to 1 and reverb works fine again.
Note that I didn't changed jack in any way.
Another thing that strikes me: There is an option called
audio.jack.multi. The documentation says:
"If 'yes' then create separate output ports for reverb and chorus effects."
However, if I set this to yes only 1 stereo output channel is created
by fluidsynth, no matter how many I specify.
