Keyboard Maestro can send MIDI messages, which effectively come from a device named “Keyboard Maestro”.  The device will be created as soon as you add any MIDI action.

You can send different kinds of MIDI packets

* Send MIDI Note On — sends a MIDI Note On message, specifying the note, velocity and channel.
* Send MIDI Note Off — sends a MIDI Note Off message, specifying the note and channel (velocity is 0).
* Send MIDI Control Change — sends a MIDI Control Change message, specifying the control, value and channel.
* Send raw MIDI packet — send a packet made up of hex bytes.

The fields for the note, velocity or controller care calculations, so you can use whatever [[manual:Variables|Variables]] or [[/Functions|Functions]] are helpful.

The raw MIDI packet must be a valid MIDI packet, and you can use text tokens to create some of the packet to allow arbitrary data to be sent.  The [[token:Hex|Hex2]] token may be helpful for formatting the data.
