How about reading the value of a single pot, calculating
the desired gains and combinations, and use multiplying
DACs to effect the fractional sourcing for each output.
Hey, you'll only need 16 DACs to cover all combinations!
Haha, that makes it clear why digitizing four channels
and computing new outputs in real time makes more sense.
Try an Arduino Zero running at 48MHz, easy programming.
Or step up to the Teensy 3.6, fast, 180 MHz. Advantage:
extensive audio libraries written by Paul J. Stoffregen.
Plug Teensy into an adapter board to use Arduino shields.
