Harmonic Field
See the HARMONY of any sound — wire a sample, a pad, a synth, or a whole mix through it and its pitch content glows on a CIRCLE-OF-FIFTHS wheel, with the detected KEY named in the centre (the in-key notes lit, the root accented). The harmony twin of the Radar: the Radar shows a sound's SHAPE, this shows its NOTES. An ANALYTICAL pass-through: the audio flows through UNTOUCHED — a zero-latency side-tap. An Analysis-family node. The kernel folds each tapped window onto the 12 pitch classes (chroma::audio_chroma) and finds the key (harmony::detect_key_from_chroma); audio.js only taps the raw samples it owns and renders the wheel. Or wire a Chord Progression / Piano Roll's Pitch output into the NOTES input and it reads the harmony from the actual notes — exact (no FFT ambiguity), synced to the Clock playhead, no audio routing needed.
