Poly Steps

Poly Steps (VST3, CLAP, AUv2)

Poly Steps is a polyphonic step sequencer MIDI effect that turns held chords into layered rhythmic figures, with each voice running its own editable step pattern in real time.

Instead of one shared arpeggiator pattern for every note, Poly Steps gives you up to 16 independent lanes. Each lane has its own step count, gate pattern, and timing feel, so polymetric motion builds naturally from a single chord. Paint steps on and off, set lane lengths from 1 to 16, and let incoming MIDI assign voices automatically, lock them to the selected lane, or wrap across the keyboard for keyboard-spanning systems.

Every active step can be shaped in detail. Per-step velocity, duration, humanize, and subdivision values are editable directly in the lane rolls, while footer controls add global Human, Velocity Random, Duration, Duration Random, and Sub Div shaping. Subdivision mode switches between Straight, Triple, and Both for tighter or wider internal pulses. SYNC locks playback to the host tempo, and AUTO modes can regenerate lane patterns every cycle for evolving figures without losing the underlying groove.

The interface is built for fast editing: color-coded lane rolls, live note labels, active-step shading, vertical or horizontal layout, lane-count control, and per-lane AUTO toggles. Twenty preset states cover starting points from minimal duos and techno bass figures to polymetric cascades, odd-meter raves, and micro-stutter systems, while header and footer dice buttons make it easy to discover new patterns and parameter combinations.

Use it for polymetric chord pulses, layered melodic sequences, generative bass motion, humanized electronic figures, evolving loop experiments, and performance MIDI that would take far longer to program note by note.
