Sebastian Tomczak’s DIY Polyphonic Drum Machine and Rhythm Looper is powered by a Teensy micrcontroller.

I’ve made a simple drum machine / looper. It is for Teensy but it can be easily ported to Arduino.

It has four sounds, a 16-subdivision pattern, variable sample rate and can playback all four sounds at once.

    ahaha! What! That little thing is awesome. It’s a good thing I don’t know how to make one of these (am srsly technically challenged) or WHOLE ENTIRE HOURS would disappear from my day.

    Very awesome little thing!
