EuclideanPbinds

A SuperCollider quark for Bjorklund euclidean rhythms — patterns, beats, and a playable Pbind wrapper.

Class	Purpose
EuclideanRhythm	Bjorklund pattern as Array, onset indices, beat-aligned seconds, post-window visualisation.
Peuclidean	Pattern subclass — yields the bit stream, composable with any Pbind input.
EuclideanPbind	Convenience constructor: bits → \note/\rest events. Passes any extra Pbind key through.
EuclideanPresets	Named rhythms: \tresillo, \cinquillo, \sonClave, \africanBell, \cumbia, \fourOnFloor, …

Quick start

// Tresillo on the default synth, 1/16 grid
EuclideanPbind(3, 8, (instrument: \default, dur: 0.25)).play;

// Cinquillo on a saw at 220 Hz
EuclideanPbind(5, 8, (instrument: \default, dur: 0.125, freq: 220)).play;

// Preset by name
EuclideanPbind.preset(\africanBell, (instrument: \default, dur: 0.1)).play;

// Modulate amp with the pattern bits
Pbind(\instrument, \default, \dur, 0.25,
      \amp, Peuclidean(7, 12) * 0.6).play;

Install

Quarks.install("https://github.com/ramonsesma/EuclideanPbinds");

Local dev: clone into downloaded-quarks/ and add the path to sclang_conf.yaml.

Test

Run from the repository root:

& 'C:\Program Files\SuperCollider-3.14.1\sclang.exe' -D -r -s --include-path 'Classes' --include-path 'tests' 'tests\RunEuclideanPbinds.scd'

Or inside sclang after loading the Quark classes:

TestEuclideanPbinds.run;

Authoring notes

The Bjorklund implementation is identical to the one in our Studio Sesma TypeScript bridge (supercollider-bridge/src/services/euclidean.ts) so sclang and Node produce the same 1/0 sequences for any (pulses, steps, rotation) triple.
