That's how > "immediate" you can get. Is that "if you specify 0 in a soundfont, fluidsynth will translate that to a 16ms release" or is that "fluidsynth is not capable of producing less than a 16ms release"? I mean, I'm happy to violate the spec for my own purposes. :) I'm basically trying to get a very aggressive staccato sound, and that's sort of difficult to do if instruments insist on tailing off in a soft (and arguably realistic) way. I can probably tolerate a 16ms release in any case. > > Is it possible? > > Well... yes it should be, but in fact it is not. > > What you're requesting is a job for fluid_synth_set_gen2() and something like > this should do it: > > foreach (c : midichannel) > fluid_synth_set_gen2(synth, c, GEN_VOLENVRELEASE, 0, TRUE, TRUE); > > This sets the generator responsible for volume release to an absolute value > of 0 for each midi channel.
