A JavaScript library for building MIDI-based web applications, providing note playback, multi-instrument support, MIDI file parsing, and soundfont loading in the browser. It converts soundfonts into browser-readable code and supports audio-visual 'synesthesia' effects.
Use cases
- play midi files in the browser
- build a web piano app with soundfonts
- play multiple instruments simultaneously with precise timing
- convert soundfonts for browser playback
- create audio-visual music visualizations
- parse midi file data streams in javascript
When to choose
- you need MIDI playback or synthesis in a web app without plugins
- you want to load General MIDI soundfonts and play multiple instruments
- you need to parse and interact with MIDI file data in JavaScript
When to avoid
- you need modern Web MIDI hardware device input support
- you need a maintained, actively developed MIDI solution
- you are building native or mobile apps outside the browser
