[Tri-Chromatic Keyboard][app]

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.

TODO:

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