midi in -- if it's a file, it auto-starts playing after a short delay, so before eg booting and running synth lab.

otherwise, it should be a value from "-listmidi"

MIDI input ports:
CASIO USB-MIDI (default)

MIDI output ports:
CASIO USB-MIDI (default)

"default" means "default" will select it. It still needs to be specified.
