Your takes never leave this device: MIDI and key input is read in this browser only, takes stay here until you delete them, nothing is uploaded and there is no account. Save a .mid file to keep a take anywhere else.
MIDI recorder in your browser
Connect a MIDI keyboard or play the computer keys, record to a metronome with a count-in, play the take back on the piano roll and save it as a .mid file.
Connecting a MIDI keyboard (Web MIDI) works in Chrome, Edge, Opera and Firefox on a computer and in Chrome on Android. Safari, iPhone and iPad have no Web MIDI, but you can still record there with the computer keyboard or the on-screen piano.
