just-intonation

32-partial additive synthesizer laid out like a 32-channel mixer. Every channel is one sine oscillator locked to a harmonic of the played note, and every channel has its own tuning, envelope and modulation.

xenharmonic & microtonal support for musescore! Just intonation, regular temperaments, chromatic staves, Bohlen-Pierce, FJS, NEJI, HEJI, HEWM, Sagittal, Johnston, Kite, ups and downs, ...

Plainsound is a sans‑serif type family of 36 fonts desgned with a quiet discipline for clarity and versatility. Integrating many OpenType features as well as Helmholtz-Ellis Just Intonation (HEJI) accidentals, Plainsound is ideal for use in articles, instruction pages and musical scores focused on microtonal music.

A complete, fast music theory library for JavaScript/TypeScript — from chord parsing and key analysis to microtonal tunings, MIDI files, notation, and audio transcription. Zero dependencies.

A pocket instrument that cannot be played badly — just intonation, an aging tape loop and a memory of its own, built for a kid on an M5Stack Cardputer-ADV (ESP32-S3)
