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.
