What it does

Draw the rhythm. It plays the level.

Each step carries a continuous level from closed to open — not a switch. That one decision is why the same instrument is a hard trance gate and a rhythmic volume sequencer depending only on how the pattern is drawn.

Ties join steps into longer events. Per-step probability makes patterns breathe instead of chattering. Pattern slots morph between each other. And the whole grid is reachable from the keyboard and readable by a screen reader, which is rare enough in this category to be worth saying plainly.

It costs about 0.11 % of real time per instance, which is roughly nine hundred instances per core.

Key features

01

Continuous level per step

Not on/off. That is the whole difference between a gate and an instrument.

02

Ties and probability

Ties join steps into longer events; per-step probability decides how often a step fires at all.

03

Drag-painting with a live playhead

Draw a pattern by dragging across the grid while the playhead runs through it.

04

Pattern slots with morph

Move between patterns continuously rather than switching.

05

Click-free by construction

The envelope's edge cases and test oracles are worked out mathematically in the design document rather than smoothed over afterwards.

06

Keyboard and screen-reader access to the grid

The step grid is fully operable without a mouse and announces its state. Genuinely uncommon in a step sequencer.
