A generative FM drum machine with a mind of its own. It writes the patterns; you steer with heat, punch in effects with your fingers, and keep the loops. Free, in the browser, on desktop and phone.
Nine voices — kick, snare, hat, perc, 808, tom, clap, metal and a granular lane — driven by a brain that writes grooves, fills and events phrase by phrase. You don't program it. You lean on it.
Heat runs from sparse and clean to dense, bright and glitching. Every voice, pattern and effect listens to it, so a single drag reshapes the whole machine.
Grooves, fills, drum events, 808 basslines and a granular lane, phrase by phrase. Leave evolve on and it keeps moving; switch it off and it holds still.
Sweep, dive, crush, gate, repeat, slice, tape stop, pump and build. Each is its own X/Y pad: touch to engage, let go and it springs home. Hold any combination.
The last eight bars are always recording. Save 1, 2, 4 or 8 bars as sample-exact 24-bit WAV loops. On a phone they go straight to the share sheet.
A 20-second granular buffer of its own output, re-sprayed in four modes, drawn the way hardware samplers show grains reading through time.
Everything you make with Dead Reckoning is yours. Use it however you like — no credit or permission needed.
Drag, tap, hold. Each panel draws what it's doing: the step ring, the heat burst, grains reading through the buffer, the countdown to the next bar.
Four-bar loops saved from the instrument, untouched apart from level matching. They loop seamlessly — that's how capture cuts them.
Everything you make with Dead Reckoning is yours. No credit or permission needed.
On a phone it folds into two pages: play (heat, the punch-in pads, save) and shape (the slow controls, grain, space, kit). Multi-touch throughout — hold three effects and ride heat with a fourth finger.
