I seem to recall on an original Rev3 Prophet5 you could microtune simply by going into a mode and turning the knobs to adjust the tuning of each note of an octave. This was easy to use and a lot of fun. It would be great if this feature could be introduced into an update for the new P5 and P10 as it would save the effort of sysex messages. Also if you could export these tunings to other synths that would be even better!
