EDU DIY Drum Sequencer
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.
