Does anyone know the syntax for this?
The closest I've gotten is:
asap $ control 4 # s "midi1" # midicmd "program"
which does send a program change message but I can't get it to send any value other than
2 for some reason.
I found some docs (here) that I'm not sure are from before SuperDirt MIDI or not. They say it's possible but don't provide the syntax:
Other types of midicmd values include "program", "touch", "polytouch", and "bend".
