Stop listening to MIDI events
First available in version 3.2 build 136.
No output parameters.
When this method is called synchronously, a return object containing the output parameters is returned to the caller immediately.
MIDI.stop disables notifications set up with MIDI.setNotify until MIDI.start is called. MIDI.stop does not clear notifications set up with MIDI.setNotify so when used with MIDI.start, you can temporarily suspend and resume MIDI event notifications.
