Okay, I stand corrected. Judging from the design of the audio drivers
and the player/sequencer, it seems like those parts were designed for
live usage only (up to now).

It seems to me like the do_not_mix_fx_to_out parameter should be a
boolean value, but the boolean datatype was introduced in C99 and
fluidsynth currently do not declare its own boolean datatype either. So
I guess that's why it is an int instead.
