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..
Controller Number | MIDI Message | Use |

128 | Pitch Bend Sensitivity | Alters the range of a pitch bend message |

15Channel 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.
