🌈 Chromatic 🎶 - Music, Math, Colour, and Free Software
summary
Chromatic maps the 12-note chromatic scale to rainbow stickers, generates printable color-coded sheet music from a tiny Python generator that emits static HTML + JS, accepts USB MIDI so MIDI input records notes and prints clean pages, and proves useful with six-year-old testers. The project’s initial commit is pushed to Codeberg and is hosted on a Forĝejo/Codeberg instance; equal-tempered tuning and Newton-inspired colour mapping are implemented rather than theoretical just intonation.
