🎹 Better than a traditional piano layout
This is an implementation of
Roy Pertchik’s Tri-Chromatic Keyboard Layout
as a web app.
You can select a scale to highlight and can optionally disable keys outside that scale.
The application supports mouse, pen, touch, and keyboard inputs.
(The keyboard support currently assumes a QWERTY layout,
which is possibly ironic for a project
focused on reinventing the keyboard.)
Uses MIDI.js for audio output.
