Appendix C - Additional Rpn Messages - M-Audio Session KeyStudio User Manual

Appendix C - Additional RPN Messages

You may have noticed that although we have stated there are 128 MIDI controller messages (0 – 127), Appendix B 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 KeyStudio keyboard in
exactly the same way as any other MIDI controller message. The RPN messages control the following:
Controller Number
128
129
130
131
*Monophonic aftertouch is not an RPN message. However, it is an additional effect message defined in the General MIDI specification and this is
why we have included it in Appendix C.
