The schematic of VOX CLONA (in attachment) gives you a precise purpose of what I would like to generate: one live voice (mine) generating an independant choir of 13 voices with its independent contrepoint projected in 3D sound space.
What's your concept for the counterpoint like? A canon is pretty easy to realize as a form for "cloned" voices. Do the other voices need to have some transformation applied to make independent melodies?
