all midi input devices
(integer value. eg: 1)
midi input device index 1
Allows for sending of remote MIDI. Device indices starts at 1, where an index of 0 implies "all".
If testing locally, beware of feedback loops, where the MIDI output is fed back into the MIDI input, causing high CPU usage and a lot of MIDI messages. If testing locally, use two MIDI devices and explicitly select the input and output MIDI devices to avoid these feedback loops
