Appendix D - Additional RPN Messages

You may have noticed that although we have stated there are 128 MIDI controller messages (0 – 127), Appendix C shows 132 assignable controller messages.. This is because messages 128 – 131 are a different type of MIDI message, defined in the MIDI Specification as RPN messages.. M-Audio has created four messages that are sent like MIDI CCs, but actually transmit a series of RPN messages.. This makes sending these complex multi-part messages as easy as sending a MIDI CC message.. You can assign these to the controls on your ProKeys Sono keyboard in exactly the same way as any other MIDI controller message.. The RPN messages control the following:
