What the xylophone stores
The xylophone runs entirely in your browser. Your chosen sound, volume, room level, label setting and, on a small screen, the part of the instrument you scrolled to are saved in your browser's local storage so they are still there next time. They never leave your device, and we do not ask for an account, a name or an email address.
If you press MIDI, your browser asks for permission to read your MIDI keyboard. Notes are played locally and are not recorded or sent anywhere.
