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.
- Allow switching instruments and configuring effects
- Choose keyboard layout mapping by swiping across keys
