Rhythm Lab

Euclidean rhythms, independent cycle lengths, rotation, accents and humanize — visible as rings.

The Rhythm Lab spreads k hits as evenly as possible over n steps — a . This single rule produces a surprising number of well-known rhythms: E(3,8) is the tresillo from Latin and afro house, E(5,16) a bossa feel, E(4,16) the straight kick.

Presets, probability and ratchets

Ten presets from world music and genres: tresillo, son clave 3-2 and 2-3, rumba clave, bossa nova, afro house shaker, dembow, UK garage 2-step, amapiano log drum and trap hats with ratchets — each with an explanation.
Click steps: the track becomes a fixed pattern; “→ Euclid” spreads the hits evenly again.
Probability 0–100 % per track: hits drop out at random — great for lively hats and percussion.
[[ratchet|Ratchet]] ×2, ×3 or ×4 per track for rolls; a new variation seed re-rolls probability and humanize.
