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".

In short, the goal behind WEBMIDI.js is to get you started with your web-based MIDI project as quickly and efficiently as possible.
