Currently parameters like “middle note”, “reference note” or “reference frequency” are supported.
However mapping keyboard keys to specific notes of a scale is not.
If you need to map multiple keys to a single note in a scale (e.g. if you have a 7-note scale and want to maintain the octave on a normal keyboard), I recommend to create a scale with 12 notes and multiple entries with the same pitch.
