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.

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
