I've attached a new file. I *think* I've done what you suggested by
sending control codes 100:0, 100:3, 6:0. Unfortunately the results are
the same: no quarter-tones with FluidSynth but Timidity plays it fine.

By the way, what does the tuning program parameter even mean? The
problem I ran into with Timidity is that if I tried to send two sysex
commands to the same note at the same time even on different channels,
it wasn't able to handle it. Would changing the program for each voice
I want fix that problem?
