Synthtopia notes that KHÔRA is a Mac‑only drone‑centric harmonic tool that uses an abstract, label‑free visual layout, where each control appears as a geometric object. A ring of stars represents just‑intonation pitches; the size of each star conveys consonance and its color signals harmonic families.
The program includes five chord generators. Genesis creates new just‑intonation chords that favor simple, consonant intervals while preserving the root note. Metabole keeps some common tones from the current chord and regenerates the remaining voices, blending continuity with change. Topos shifts the whole chord through just‑intonation space while maintaining its internal structure, revealing more distant microtonal colors.
Two hidden generators broaden the palette. Skia explores darker, modal harmony over a fixed drone, using spacious minor voicings that return to the home chord every fourth generation. Helios, the sole mode based on 12‑tone equal temperament, offers modern color harmony with smooth bass motion and a similar return pattern.
KHÔRA is currently available under a “name a fair price” model, letting users choose their purchase amount.
