STOMPER is a drum generator for Eurorack that uses an unfiltered square-wave oscillator. Quickly sweeping the oscillator results in a satisfying high-q-sounding zip and thud due to all the crazy harmonics.
All inputs can be CV controlled (0-5V), including the built-in clock-divider. It uses standard 10 pin +12/-12 power, drawing a paltry 30mA.
It’s triggered by sync-24 clock, trigger/gate, or button press. It has a handy gate output to easily (and accurately) apply an envelope to each hit whether it’s triggered or clocked (you can see the gate in action in the video below as it triggers the oscilloscope.) Output is 10Vp-p.
-Glorious 1 bit audio.
-CV on all controls.
-Gate output for external ADSR (or whatever).
-Clock or trigger input.
-Arduino-compatible programming header, code provided.
-Unused I/Os broken out for hacking.
