Grid

- Column headers with beat numbers and playhead highlight
- Page navigator — Prev/Next buttons for multi-page patterns
- Row stack — scrollable rows, each containing a strip of grid cells
- Row controls — clip selector, note selector, velocity dial, mute/solo, scale/nudge steppers
Pattern Presets

Transport Controls
BPM
The BPM field shows the current tempo. In standalone mode, click the field and type a value or use the up/down arrows to adjust (range: 20–300). In plugin mode, the field is read-only and displays the DAW’s tempo.
Time Signature
Two number fields control the time signature:
- Numerator — range 1–32, steps of 1
- Denominator — cycles through 1, 2, 4, 8, or 16
The denominator determines how the grid is divided:
- Denominators 1, 2, 4, or 8 — each beat is split into two columns: the beat and its ”&” (offbeat). For example, 4/4 gives 8 columns, 7/8 gives 14 columns
- Denominator 16 — each beat is a single column with no split. 10/16 gives 10 columns
Swing
A rotary dial that shifts offbeat (”&”) columns forward in time, creating a swing feel. Drag vertically to adjust. Display range: 0–66.6%. Swing only affects beat-split grids (denominators 1–8); 16th-mode grids are unaffected.
Play / Stop
- Standalone: a toggle button that starts and stops the internal transport
- Plugin (DAW-hosted): a read-only badge showing the DAW’s current play state — transport is controlled from the DAW
Global Mute / Solo Clear
Two small circular buttons in the transport bar:
- M — lights up when any row is muted; click to clear all row mutes at once
- S — lights up when any row is soloed; click to clear all row solos at once
View Toggles
- Animate — enables playback flash animations on cells as they trigger. The playhead column highlight is always visible regardless of this setting
- Transcription — switches between two cell display modes:
- On: cells show rhythmic notation — horizontal pills representing the clip’s MIDI notes, with vertical position reflecting pitch and opacity reflecting velocity
- Off: cells show a single dot per active step
- Monitor — when enabled, clicking a row’s note up/down arrows plays a one-shot MIDI preview of that row’s root note
