WEBMIDI.js is a JavaScript library that simplifies interaction with the Web MIDI API in browsers and Node.js. It provides user-friendly functions for sending MIDI messages (like playNote, sendPitchBend) and event listeners for receiving MIDI input (like noteon, pitchbend, controlchange).
Use cases
- send midi notes from a web page to a synthesizer
- listen for noteon events from a midi keyboard in the browser
- control midi instruments with pitch bend and control change messages
- build a web-based midi sequencer or drum machine
- handle sysex messages from midi hardware
- connect a midi controller to a node.js application
- react to program change messages from midi devices
When to choose
- you want a friendly, high-level API over the raw Web MIDI API
- you are building a browser-based music app or instrument controller
- you need cross-environment support (browser and Node.js)
- you want simple event-driven handling of inbound MIDI messages
When to avoid
- you need low-level, direct control of the Web MIDI API without abstraction
- you are working outside JavaScript or in an environment without Web MIDI/Jazz plugin support
- you need audio synthesis or DSP rather than MIDI messaging
