Here I show how to process audio in CHOPs to generate triggers that I further process into ordered and random patterns. I then use those impulse patterns to drive a Vellum grain simulation.
The audio used from Six Umbrellas, it’s a song named Downfall. It is used under Creative Commons, and can be downloaded here
