Description

Most drum sequencers are complex machines – packed with buttons and LEDs, all driven by a microcontroller. For this DIY Drum Sequencer kit, MKi and Erica have 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.

NB! All kits in these series are simple and come with extensive user manuals which can be downloaded separately, therefore we will not provide customer support in case your DIY build fails to function or similar.

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
  • Width: 34HP
  • 27mA @+12V; 20mA @-12V
