This may have been mentioned in other posts but I can’t recall a specific one.
Set-up:
Scaler playing a Performance feeds into a Mono voice synth.
Since the Mono instrument plays one voice most of the notes in the Performance are ignored, but little melodic motives appear. I hit on this with the obvious “accident” of switching to a mono synth while a Performance was playing.
By muting, unmuting and changing the pitches of a MIDI track, originally recorded from a Performance, it is possible to change which melodic motive “leaks” through. However, said “melodies” are somewhat random and depend on the note-stealing set-up used, etc.
Admittedly this is a hit and miss way to create music, but I’ve found a few interesting sounds doing this and so thought it was worth a post.
