@music-i18n/verovio

Forked version of Verovio that includes music-i18n fixes. Music internationalization refers to the process of adapting music software to work with non-Western Common Practice structures, such as microtonality.

Verovio is a fast, portable and lightweight library for engraving Music Encoding Initiative (MEI) music scores into SVG.

See it running in the browser and check out the tutorial for its web integration and for enabling user interaction.

This fork

This fork is about adding full support for "music-i18n" (music internationalization) to Verovio. This includes:

• Supports all SMuFL accidental glyphs. Not all bundled fonts support these glyphs, so make sure to use Bravura.
• Fixes MIDI SysEx export which is broken on the main trunk.
• Supports MEI temperaments for MusicXML via the element sound/play/other-play[@type = "tuning-mei"]
• Supports full microtonality via Ableton ASCL tunings for both MEI (via option tuningFile) and MusicXML (via both option tuningFile and MusicXML element sound/play/other-play[@type = "tuning-ableton"]).

Basic usage

The recommended usage of the package is with ESM. Use .mjs as file extension when using this directly in Node.js or set "type": "module" in your package.json.

import createVerovioModule from 'verovio/wasm';
import { VerovioToolkit } from 'verovio/esm';

const VerovioModule = await createVerovioModule();
const vrv = new VerovioToolkit(VerovioModule);
vrv.setOptions({
   tuningFile: await (await fetch('/path/to/tuning.ascl')).text(),
   font: 'Bravura',
});
vrv.loadData(await (await fetch('/path/to/score.mei')).text());
const svg = vrv.renderToSVG();
const midi = vrv.renderToMIDI();
