Fons,
You can pull it to the correct pitch with the pitch
bender.
I stick a piece of paper besides the wheel to block it to the
correct position - it's just within range :-)
as always it was *much* simpler. Fluidsynth has a command line switch,
and even qsynth has preferences where I can select: jack @ 24/48.
I just have connected the output of fluidsynth to jack-rack, loading a
tremolo and a reverb. Guess what I'll do the next hour ;-) .
Best regards
ce
