Hi,
This applies to the OB-6 (which I have), but I think it also would apply to the Prophet 6 and REV 2.
I'd like to see a new Seq Pedal Mode function that turns Record on and off for the sequencer. This would allow a person to simultaneously transpose the sequence while playing along, keeping both hands on the keyboard at all time. This might be best realized with the REV 2 because of its split feature, but many products (including my beloved OB-6) would benefit.
Additionally, a Seq Pedal Mode function that turns Record on when pressed and then switches immediately to play when unpressed could make for a cool looper feature, provided that the played tempo and the playback tempo are (roughly) the same.
