Currently, MIDI can only be used for live playback. Playing .midi files is planned in future updates. To use MIDI compat:

Select a valid MIDI device in the config menu (press ; )
Right click a Keyboard Relay block with a Stop Master in your hand, then place the Stop Master
Set the tuning frequency on top of the Stop Master (or don't)
For any note you wish to activate, place a receiving redstone link with the tuning frequency first and the specific note frequency last.
Right click the Keyboard Relay to start playing!

(I will upload a tutorial on how to use it soon)
