Philip Glass Riff Automaton

"In which we create a Philip Glass Riff Automaton in order to be able to simply put our feet up and listen forever.

About a week ago I saw a random tweet of a YouTube video organ piece from Satyagraha, and for some reason it came to me that I could have the riff play and then alternate between two different versions of it. Well, it took me almost that whole week to get it working but I'm pretty happy with the results. I could see taking this and going much further with it—having more than two parts , for example, as well as adding harmonies, counterpoints, and bass drones—but for now this is a good proof of concept showing it's indeed possible to get it working. Had to figure out how to get all the logic flowing properly, and luckily Voltage Modular has a good selection of switching and logic modules available.
