Music: Heathens by Twenty One Pilots Credit to @RockstarLorry for the source project. I found a way to sync costume changes with the beat of the song. I run a routine that captures the beats that I tap on the Spacebar. Then I change costumes when each recorded, elapsed time comes up. Compare it to the original (which is actually very well synced, but not perfect).
