This is useful for synths that have multiple monophonic channels. This M4L device works conjunction with PathMIDI.Receive in order to send and receive the MIDI data. Poly2Mono8 splits up the chord and sends it to PathMIDI.Receive.
Create a MIDI track for the polyphonic material and insert Poly2Mono8. For each monophonic output, create a MIDI track and insert PathMIDI.Receive. Set each PathMIDI.Receive device to receive from successive PathMIDI busses.
