KHÔRA - Microtonal Soundscape Synthesizer

video upload by Laboratory 0

"KHÔRA is a drone-based harmonic instrument. There are no labels - every control is a living geometric object. The ring of stars is a map of just-intonation pitches. Star size represents consonance, while color represents harmonic families. Rather than relying on theory, a keyboard, or parameter lists, KHÔRA offers a new way to explore harmonic space through interaction.

Five built-in chord generators:
Click the Seed (center-left icon) to generate a chord. Right-click to switch modes.

1. Genesis: Generates a new just-intonation chord, favoring simple, consonant intervals while always retaining the root.

2. Metabole: Preserves some common tones from the current chord while regenerating the remaining voices, balancing continuity and change.

3. Topos: Moves the entire chord through just-intonation space while preserving its internal structure, revealing more distant microtonal colors.

4. Skia (Hidden): Explores dark, modal harmony over a fixed drone, with spacious minor voicings that return to the home chord every fourth generation.

5. Helios (Hidden): The only mode based on 12-tone equal temperament (12-EDO), featuring modern color harmony with smooth bass motion and a return to the home chord every 4th generation."
