AUM - control Eventide apps pitch with MIDI Keyboard
I'm a total noob with AUM. I have Eventide Crystals and Shimmerverb. They both have knobs to control pitch. I am wondering is there a way to map the MIDI keyboard to control these. It would make musical sense, but I can figure it out. I would be great to say have C3 as 0, then pitch up and down from that, to set the pitch knob in those increments, ie + 5 semitones, -7 semitones etc.
Any ideas if this can be done? Or in conjunction with another app?
