I go through the original 48 factory presets (I accidently said it was only 40 in the video) from the Prophet-5 that are in the Prophet-6 and where I first heard those sounds.
Are you sure it wasn't 40? (Then the Rev 3.3s had 120 anyway). 11-18, 21-28, 31-38, 41-48 & 51-58.
Anyway, yeah about the idea put about that the P6 sounds harsh. Mine doesn't at all. It depends who has programmed it.
