Full Release Notes


### Added
- **New effect: Chromatica — the screen tunes to the song's key.** Twelve rings on the circle of fifths bloom with the chord being played, and the whole mandala takes the hue of the detected key, with minor keys drooping and cooling. A Consonance toggle strings tension lines between simultaneously sounding notes — warm for a fifth, tense violet for a tritone. A new `audio.key_hue` binding source lets any layer lock its colour to the current key.
