While the MIDI standard is based on 12-tone equal temperament, you can map the “notes” on your MIDI device to any pitch defined in a Mus2 tuning.
- In your score’s window, choose Tuning from the Score menu.
- From the list on the left side, select a tuning.
- On the right side, go to the MIDI Key Map page.
- Define any necessary key mappings in the key map table.
- Keyboard column shows each MIDI note.
- Accidental column indicates the accidental assigned to this note
- Note Treble Staff Level column shows which note on the staff the MIDI note corresponds to.
- Raise or lower note levels when changing between sharps and flats option will increase the note level by one when switching from an accidental with a positive value to one with a negative value. The reverse occurs when switching from a negative accidental to a positive accidental. This ensures that notes with sharps get their frequency from the note one step below, while notes with flats get their frequency from one step above.
MIDI key mappings are associated with each specific tuning entry in a score. To make sure you’re using the correct tuning while recording, give this tuning a unique name, e.g. “Beyati mapped”. You can also duplicate the tuning before mapping if you wish to keep the original one as is.
You can define the key map for a scale without filling out all of the MIDI notes in every octave. The mapping for empty MIDI notes are inferred from the defined key mappings.
