A JavaScript/TypeScript library for reading and writing MIDI files, converting them into a friendly JSON format. It is designed to work seamlessly with Tone.js but can be used standalone in Node.js or the browser.

Use cases

  • parse midi files into json in javascript
  • convert midi to tone.js format
  • read notes and tempo from a midi file in the browser
  • generate and write midi files from javascript
  • extract track and control change data from midi

When to choose

  • you need to parse or generate MIDI files in JavaScript or TypeScript
  • you are building music apps with Tone.js and need MIDI input
  • you want a simple JSON representation of MIDI note, tempo, and control data

When to avoid

  • you need real-time MIDI device input/output rather than file parsing
  • you need advanced MIDI editing features beyond reading and writing standard files
  • you work outside JavaScript/TypeScript environments
