If a keyboard or midi instruments has a specification which indicates 128 note polyphony. What is the best way to test and verify this? Anyone have any ideas. Using a DAW I was going to send all 128 notes as long note and then turn each one off one at a time and see if I can the see each note turn off either in spectrum from or in Melodyne. Does anyone have a better idea how to do this? bit of brain fog this morning.
