Felix Thorn aka Felix's Machines, uses computer to control analog, traditionally, hand-played instruments. Much like the player-pianos of their time, however, possibly not as simple in comparison (and involving creativity beyond the novelty). The computer here controls spring-controlled sticks hitting real drums, piano-hammers, glockenspiels, etc. >>Watch his videos if you can<< Thrown in for added visual spark are LED meters, and the like.
