MIDI Recorder

The simplest way to record MIDI.

Records right away, no install or setup required. Automatically connects to new MIDI devices.
Visualizes notes, pitch bends, and instrument changes, as you play.
Recovers recordings in case the browser crashes, or you close the tab by accident, or refresh the page, or there's a power outage.

If you've got a MIDI keyboard, plug it in and try out the app!

Built with SimpleMidiInput.js and MidiFile.js, and written in CoffeeScript.
