RollPress once. Find something new.

18 quintillion grooves.

Every roll draws a 64-bit seed. The groove, its sounds, its name and its artwork are all computed from that one number, so the same seed plays the same groove on any device. No two rolls are alike: we rolled 5 million and found no repeats.

Found one? Keep it.

Every groove you roll keeps its own name and artwork, so you can come back to it, send it or build a track from it.

A lock on every step

Any parameter can change on any step. A sound lock swaps the whole engine for a single hit. Draw locks, roll them or record them live.

Engines, not presets

Analogue models, FM, samples, physical models, inputs and synth voices, plus effects. Built for sound first.

What is insideMultitrack, in four parts.

Rolls and share links

A groove fits in a link of about 40 characters. It plays on any device with no server round trip. Same link, same groove.

Multitrack, in four parts

Drums, bass, chords, melody. Mute, lock or roll a whole part with one key. A sample-accurate sequencer keeps every part in time.

Parameter locks

Up to 64 locks per pattern, drawn as a lane under the steps it belongs to.

Four places, one sound
