Most drum sequencers are complex machines – packed with buttons and LEDs, all driven by a microcontroller. For the mki x es.edu DIY Drum Sequencer kit, we decided to take the opposite approach: a hands-on rhythm engine with a minimalist interface, built from just a handful of logic chips. Each of the sequencer’s four channels is programmed in real time using a single button. Patterns loop automatically, can be shortened on the fly, and support half-time playback for slower, evolving grooves. Accents are handled using synced LFOs, while a simple resistor-DAC turns patterns into stepped control voltages – perfect for modulating pitch, decay, or other parameters. Whether you’re looking to learn about sequencer design, sharpen your soldering skills, or just want a drum sequencer that plays like an instrument, this DIY kit packs surprising depth into a refreshingly simple interface.

Features

  • 4 independent channels with one-button step input/removal
  • 16 steps per channel, individually reducible to 12 or 7
  • Optional half-time mode per channel
  • Two syncable analog LFOs for dynamic accents
  • Resistor-DAC output for pitch or decay modulation
  • Internal clock with 16th, 8th, and quarter note outputs, syncable to external gear
  • Module width: 34HP 
  • 27mA @+12V; 20mA @-12V

There’s nothing quite like the sound of old-school analog drum machines. Especially classic kicks like Roland’s 808 and 909 are ubiquitous in electronic music. Unfortunately, their circuitry is notoriously complex and difficult to understand. Enter the mki x es.edu DIY Kick Drum kit, which not only aims to shed some light on the fundamental circuit design principles behind those circuits – but also captures their unmistakable sound as a fully-fledged Eurorack module.

EDU DIY Hi-Hat
EDU DIY Hi-Hat

Synthesized, analog Hi-Hats are pretty fascinating. That’s because emulating any kind of cymbal using an analog circuit is tough since the sound a real cymbal produces is not quite pure noise, but also not really harmonic. Still, a couple of classic drum machines like the Roland TR-606 and TR-808 took their best shot at it, with quite strange-sounding results that have since become iconic in electronic music. Inspired by this, we decided to follow suit and continue our percussion-focused second season of educational DIY kits with the mki x es.edu DIY Hi-Hats.
