|
|
|
|
```js
|
|
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);
|
|
```
