PM_E‑2 PolyMeter Editor — Notation
The second-generation editor, built around proper engraved drum notation. Design a groove and read it as a real percussion staff — the same program string still plays identically on every form factor.
What it is
Where the first-generation PM_E‑1 editor is built around a step-pad grid, PM_E‑2 is built around notation. Grooves render on a 5-line percussion staff engraved with the Bravura music font (the open SMuFL standard used by professional scoring apps): real noteheads (X for cymbals, filled for drums), stems up for hands and down for feet, group-aware beaming, accents, ghost notes in parentheses, and the full ornament vocabulary — flams, drags and rolls. You can edit directly on the staff: click a step to cycle its dynamic, Shift-click to cycle its ornament.
Three views share one engine: the Staff, a TUBS grid (Time Unit Box System — the clearest way to read odd meters, polyrhythms and West-African bell patterns at a glance), and a Konnakol syllable view (South-Indian solkattu — “ta ka di mi”) for spoken rhythm. Clave patterns are detected and labelled (2-3 / 3-2). It's zero-install, runs in any modern browser, and works fully offline.
Everything you design saves to the same compact program string in the shared share-language, so a groove built here loads into the original editor, the hardware concepts, or an embedded widget and plays back identically everywhere.
Embed the editor (or any device) elsewhere with one <div> + a script —
