Oh Derek

Synthesized drum machine

Drums that breathe. Oh Derek builds every hit from scratch — no samples needed — and moves each lane through four sounds while it plays: a kick that turns into a tom, a snare that becomes a gated room, metal that bends from a pipe into scrap. Industrial at heart, ready for anything with a beat.

What it does

Five lanes, all synthesis

BODY (FM drums with a growling filter), SNARE, MACHINE (waves and noise), METAL (a modal engine of ringing bars, plates, pipes, bells and scrap) and HIHAT. Every sound is made as it plays.

A dot between four sounds

Each lane puts four sounds at the corners of a pad. Drag the dot and the drum morphs between them: a kick, a low tom, a rim and a clap in one lane.

Motion

Let the dots move by themselves, in time with the song: circle, figure 8, spiral, Lissajous, square, random — or draw your own path and Oh Derek plays it back.

A sequencer for each lane

Up to 32 steps per lane, each with its own length and rate (1/16, triplets, 1/32), so lanes drift against each other into polyrhythms. Euclid fills, swing and gate.

Steps with character

Every step chooses a corner, a pitch, a velocity, a chance and a ratchet of up to four hits. One pattern, endless variation.

Metal from any sound

Load a WAV into METAL and it becomes a material: its ringing partials turn into a resonator you can bend into scrap, a plate or a bar — or excite with the sound itself.

Synth, wave or sample

BODY, SNARE and HIHAT play their own synthesis, a built-in wave or your sample; MACHINE scans through 16 built-in waves or a wavetable from your file.

Generator

Pick a style — techno, industrial, house, electro, drum & bass, trap, dub, ambient, broken, chip, tribal, hard — set tempo, how busy, how much the dots fly and how wild. Generate. Undo.

Mutate every lane

One click shakes a lane's sound into a new variation; another takes it back. Shift-click for just a little.

Effects and GRIND

Every lane sends to chorus, tape echo, delay and a shimmer reverb. GRIND drives the whole kit, and each lane has its own envelope, mute and solo.

16 factory kits, 80 lane sounds

Kits with 32-step patterns and moving dots, from industrial techno to dub, trap and chiptune. Every lane of every kit is a preset too, so you can mix the kick of one with the snare of another.

Plays with your DAW

Follows the host's tempo and transport, or runs on its own with PLAY. Play every lane from MIDI; channels 2–5 hit the corners directly.
