So FOLD, what it does, is to colapse/hide all the Rows/lines without MIDI notes, and only showing us the ones you want to work for… an example can be: F, G, A#, D, F, G A, and that are the only notes you will see in the MIDI editor when you FOLD, its indeed a great helper and the task to compose in a scale you dont know very well, becomes really easy
but doesn’t fold show only the notes that are already in the editor? What if you only have 6 of the 7 notes in your scale already in there?
