- Summary
Gingoduino is an open‑source music theory engine designed for embedded platforms such as Arduino, ESP32, Teensy, Daisy Seed, and Raspberry Pi Pico. Licensed under MIT, it supplies core musical concepts-including notes, intervals, chords, scales, and harmonic fields-alongside a fretboard engine for instruments like violão, cavaquinho, bandolim, and ukulele, complete with fingering scoring. The library supports a 12‑note chromatic system with enharmonic equivalents, 42 chord formulas with reverse lookup, and over 40 scale types and modes. It also handles musical events (notes, chords, rests) and sequences with tempo and time‑signature control. The project is hosted on GitHub for community collaboration.
