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.
