// Audio triggered DRUM, inspired by analogue drum brains like Simmons SDS-V oder Tama Techstar. Played with drumpad on audio in. With headphones on you can use the internal mic as trigger source.

// An integrator on env0 and env1 mimicks the capicitor of a decay envelope found in most analogue drum modules. coef1 controls this.

// True happiness comes from parallel distortion. Wet/Dry-function for better transient and cleaner fundamental.
