Stumbled upon this on youtube. Thought it was pretty interesting idea other than the fact that the faders sound like they are crying out in pain. I am sure with with better faders (use touch sensitive faders that disengage the motors when moved) and a better way of selecting challenges (and throw in some more challenges) this could have some potential. It definitely would keep me occupied in-between gigs.
