WEBMIDI.js — Send and receive MIDI messages with ease

If you don’t want to directly use the Web MIDI API, you can use WEBMIDI.js

WEBMIDI.js makes it easy to interact with MIDI instruments directly from a web browser or from Node.js. It simplifies the control of physical or virtual MIDI instruments with user-friendly functions such as playNote(), sendPitchBend() or sendControlChange(). It also allows reacting to inbound MIDI messages by adding listeners for events such as noteon, pitchbend or programchange.

Works like a charm. Initialize it, and start listening for events.

See the Pen WebMidi.js by Bramus (@bramus) on CodePen.

In the browser you can include a self-registering script to get it. ESM and CJS flavors are also available.
