* annotate pure values with their value, allowing single mininotation values to maintain their labels as pure * Don't use any 'patternified' arguments if they're all 'pure' * allow pattern weights (roughly, beats-per-cycle) to be inferred where possible, including from mininotation and across many transformations (e.g. `fast` with a 'pure' factor) * Add `beatCat`, similar to `timeCat` but funkier * `silence` has a weight of 1, add alternative `nothing` with a weight of 0, and `gap` function with weight argument * preserve weight across applicative operations (weight comes with the structure) * add `stack` alternatives that take advantage of pattern weights to align patterns differently - `stackLeft`, `stackRight`, `stackCentre`, `stackExpand`, with `stackBy` with an argument for patterning the alignment.
@strudel/core
This package contains the bare essence of strudel.
Install
npm i @strudel/core --save
Example
import { sequence } from '@strudel/core';
const pattern = sequence('a', ['b', 'c']);
const events = pattern.queryArc(0, 1);
const spans = events.map(
(event) => `${event.value}: ${event.whole.begin.toFraction()} - ${event.whole.end.toFraction()} `,
);
yields:
a: 0 - 1/2
b: 1/2 - 3/4
c: 3/4 - 1
a: 1 - 3/2
b: 3/2 - 7/4
c: 7/4 - 2
