MIDI Editor

The MIDI editor allows you to create or edit a MIDI event. This lets you specify the type of MIDI event to send or receive, as well as the optional channel, value, and other parameters pertaining to the selected MIDI event.

OnSong supports a number of types of MIDI events. Pick one of these types to learn how to configure it for you needs.
