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:
Controller Number MIDI Message Use
128 Pitch Bend Sensitivity Alters the range of a pitch bend message
129 Fine Tune Adjusts the tuning of your sound module or synthesizer in small steps
130 Coarse Tune Adjusts the tuning of your sound module or synthesizer in large steps
131 Channel Pressure 15 Adds an effect such as vibrato or brightness, depending on the instrument
settings and capabilities
15
Channel Pressure 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 D.
