-		InputEventMIDI allows receiving input events from MIDI (Musical Instrument Digital Interface) devices such as a piano.
-		MIDI signals can be sent over a 5-pin MIDI connector or over USB, if your device supports both be sure to check the settings in the device to see which output it's using.
-		To receive input events from MIDI devices, you need to call [method OS.open_midi_inputs]. You can check which devices are detected using [method OS.get_connected_midi_inputs].
