@strudel/edo

This package adds EDO scale functions to strudel Patterns.

Install

npm i @strudel/edo --save

Example

import { n } from '@strudel/core';
import '@strudel/edo';

// E.g. edoScale for Gorgo-6 scale, 16 EDO, LLsLLLs
// base note C3, large step size 3, small step size 1:
// C3:LLsLLL:3:1
const [baseNote, sequence, largeStep, smallStep] = ['C3', 'LLsLLL', 3, 1]
const pattern = n("0 2 4 6 4 2").edoScale([baseNote, sequence, largeStep, smallStep]);

const events = pattern.firstCycle().map((e) => e.show());
console.log(events);

yields:
