Region Automation: Control Change 30

Open/Set Region Automation to Control Change 30 (CC30). It is possible to write “programs” for MIDI devices that aren’t notes being played.

The MIDI specification lists CC30 as “undefined”. Device (software) manufacturers are free to use CC30 for their own purposes.

You can find the standard definitions of continuous controllers (CC) in the latest version of the MIDI Implementation Chart v2.
