Control tempo by midi - is it possible?
I'm making a song that speeds up and slows down at certain points, and I'd like to be able to control it with a foot pedal. Either an expression pedal, or a pair of footswitches that increase and decrease by a few bpm per click. I'm planning to use looping while playing and recording other instruments, and I don't think I can twiddle the tempo knob accurately enough at the same time.
Is it possible to control the deluge's tempo by midi? Or any other way?
I know it can sync to an external clock, but I don't know how to achieve what I want with any other device either.
