That's some pretty ambitious automation. Sounds surprisingly good, too. That'd be a helluva thing to have in the family room.
Reminds me of a Mighty Wurlitzer
http://www.organstoppizza.com/wurlitzer.htm I saw once in Grand Rapids, MI. There weren't that many of them built, because they were so large and complex you almost had to build a building around them, rather than move them into a building. They were huge, involving a whole orchestra of instruments, including a massive pipe organ. Kinda like a giant synth that didn't play samples, but actual instruments. They were all like the guitars pictured above, where there were pneumatic actuators, solenoids, valves, servos, etc. to play the instruments. Huge room full of air compressors, turbines and bellows plumbed to operate it all, and a monstrous keyboard that came rising up out of the floor on a platform at the beginning of an act.
The wide variety of horns and other wind instruments, percussion, strings, and various sound effects were built into, onto, or hung from the walls in ceilings of the building. There were windows so you could see the air plant that fed all this stuff, as it was pretty amazing all by itself.
The most amazing? Not a speaker or amplifier in the place. It was all real, and all acoustic. Sounded incredible.
