EDU DIY Drum Sequencer

A drum sequencer of the mki x es.EDU series, Erica Synths' collaboration with Moritz Klein, that takes the opposite way to most: no microcontroller, a handful of logic chips and a minimalist interface. Each of its four channels is programmed in real time with a single key, its pattern looping, shortened on the fly or played at half time; two synced analog LFOs handle accents, and a resistor DAC turns each pattern into stepped voltages.

Key features

• Four channels of 16 steps, reducible to 12 or 7, one key each
• Half-time mode per channel, gate and CV outputs per channel
• Two syncable analog LFOs for accents
• Internal clock with 16th, 8th and quarter note outputs, external clock input
• 34 HP, 27 mA on +12 V and 20 mA on -12 V
