Octavia

🎻 Event-driven multi-standard MIDI state-tracking library. Working with MIDI should be simple, while faithful and professional.

Made with ❤️ by Lightingale Community.

Visit our repo on Codeberg or GitHub for more info. You can also see the demos in action.

Warning

Octavia may work on Node.js, but support for it is never intended. Apart from browsers, only Deno and Javy are supported.

Octavia is only ever published to Deno Deploy and JSR. If you see Octavia published to other registries, report those fake packages immediately as they may contain malware.

Files

Only files ending in .mjs are meant to be used as a library. Files prefixed with xp_ are tested to work on Windows XP (Chrome 49 and Firefox 52 ESR).

• state.mjs: MIDI processing core.
• basic.mjs: The bare minimum to get you started on writing visualizers. Requires state.mjs.
• cambiare.mjs: Batteries-included full-blown visualizer as a module.
• micc.mjs: The streaming assembler and disassembler for standard MIDI files.
