This was just a test-drive of my guitar controlled rack. But think it points a light in a very interesting direction.
The patch sends values from the guitar to the rack base on 6 (midi) pitch slots between 40 and 64 (using sigmund~). The amplitude in those slots controls the values for 3 parameters per effect [1..6].
Three channels/audio outs were sent to stereo wave files 1) after the eq7 (diy2), 2) after the first effect, and 3) after the whole stack.
The two effects used were pitchshifter>a delay (triple bodyresonace (also diy2)).
May you find it amusing. If not inspirational.
