If I run fluidsynth from the terminal
fluidsynth soundfont.sf2 midifile.midi
I am then able to write control change commands in realtime to alter the
playback. For example,
cc 1 7 0
sends a CC#7 message (channel volume) to channel 1 with a value of 0.
Now, I would like to specify a bunch of these cc commands when calling
fluidsynth, meaning that the channel volumes are set *before* playback starts
(in turn meaning that I can output my desired mix to an audio file, which is my
end goal here).
When reading the fluidsynth [manual][1], I find the following option:
-f, --load-config
Load command configuration file (shell commands)
I'm guessing this is what I want to use, since control change events, further
down in the fluidsynth manual, is listed under MIDI MESSAGES, which in turn is
listed under SHELL COMMANDS. However, the manual doesn't give me much to go on
here (the quoted passage is the only info about this option that I can find).
I've tried reading up on [configuration files in UNIX][2] without being able to
resolve anything.
I've tried making a file called `config`, filled it with a bunch of cc
commands, like so:
cc 0 7 0
cc 1 7 0
cc 2 7 0
and then tried to load it by using
fluidsynth -f config soundfont.sf2 midifile.midi
but this approach doesn't do anything (fluidsynth doesn't report any error
either).
