909-Style Groove Sequencer

μ-onOne click per step.

A quick, hands-on groove box for your DAW or on its own. Build a beat from kick, bass, hat and snare tracks on a 16-step grid, add a dark techno rumble, and let the bass duck from the kick for the classic pumping groove.

Good to know. Some things are not in μ-on yet: per-step pitch for the bass, loading your own samples, and pattern banks. Feedback is welcome on the contact page.

A groove box,
built from tracks.

Every track has a row of sixteen steps and a sound engine that plays them. Switch a track’s engine at any time and it keeps each engine’s settings.

One to eight tracks

A new μ-on starts with one Kick track. Add tracks, reorder them by dragging, and each keeps its own settings, steps and colour.

Tracks

Sixteen-step grid

Left-click a step to switch it on or off, right-click to accent it. Swing pushes every second sixteenth later for a shuffle. Every engine starts with its own groove, such as four-on-the-floor for the kick.

Steps

Kick and Bass engines

A synthesised kick with a fast pitch drop and a drive stage. A deep bass with a sub oscillator, a filter with its own envelope, and drive. Raise Sub, Drive and Reso for a gritty rumble.

Synthesis

Hat and Snare

Built-in drum sounds that play one shot on each step, with tune and decay. You can’t load your own samples yet.

Drums

Rumble

Not a drum you step. Rumble takes the sound of another track and runs it through drive, three tempo-synced delay taps, a dark reverb, a volume envelope you draw, and a filter. The classic techno rumble.

Rumble

Sidechain, modulators and mixer

Make the bass duck from the kick in the mixer. Eight modulators per track, the shared mixer and effects, and presets, the same as the rest of the μ-series.
