As I said in a comment to http://fluidsynth.resonance.org/trac/ticket/1
, the problem is that we never get through the attack phase. So I still
think delaying the note-off could be a good workaround. But Christian
could perhaps suggest a good default value for the delay?

Assuming midi.mode (or better, synth.midi-mode) will be used to change
between gm, gs, xg etc, it does not make sense to add no-off-percuss to
that series since it might control more things (e g ignore bank
selection in GM mode).
Better to use a separate setting for this problem then, something like
synth.note-off-percuss=delay/ignore/process. And for now, hardcode
percussion channel to 10 (as already done in a few places).
