Step sequencer · in your browser · free

Music in rings,
played live.

Orble is a sequencer for live, improvised electronic music. Every track is a ring of steps turning at its own speed — so loops drift against each other into polyrhythms. Shape the sound with big macro knobs, switch whole groups in time, and perform it.

No account, no install. Best in Chrome or Edge on a computer.

How it works

Four groups, A to D, each with up to eight tracks. One group plays big in the middle of the stage, where you shape it; the other three keep turning at the side, ready to bring in.

The whole Orble stage: the big group with its rings, macros and step lane on the left, the track editor in the middle, and three more groups on the right

The stage: the big group's rings and macros, its tracks and editor, and three more groups waiting on the right. Click the picture to see it full size.

Built for playing live

Everything is quantized to the music — mutes, scene changes, tempo, chords land on the beat — so you can improvise without breaking the groove.

Rings & polyrhythm

Each ring has its own length and speed. A 16-step hat against a 7-step perc and a 12-step bass: patterns that never repeat the same way.

Synths built in

Analog (with unison), FM, Wavetable and a drum machine — plus your own samples and external MIDI synths. Lock any sound per step.

Macros & controllers

Eight big knobs per track and three banks per group. MIDI-learn any knob to your controller and record your moves into the steps.

Generate & corrupt

Start from a generated beat in a style — techno, house, breaks, dnb, ambient… — and let Corrupt slowly mutate it while you play.

Harmony

One key for the whole set, chord progressions on a bar, and tracks that follow the chord — so basses, stabs and arps stay in tune.

Perform & record

Arm mutes and fire them on the next bar, hold a group in a loop, crossfade between groups, fill, repeat, sweep — and record the whole jam to a WAV file.

Your first minute

The first time you open Orble, a short tour shows you around. The gist:

Generate a beat

Press the sparkle button on a group, pick a style, and a whole beat lands on the next bar.

Play

Press Shift+Space (or the play button). The rings start turning.

Shape it

Click a ring to open its track, then turn the macro knobs on both sides of the rings.

Perform

Mute tracks with M, arm several with A and fire them together with Space.

Play together Coming soon

Up to four players in a room, each playing one group, all hearing the same music in time — over the internet. It's built and being tested; it opens after the first release.
