Houdini CHOP Talk 4 Audio Processing 2 Triggers

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.
