Negative Harmony vs MultiComb

Negative Harmony lets you explore one of music theory's most fascinating transformations: reflecting any chord or progression across a tonal axis to produce its harmonic mirror image. TAP ANY CHORD Select a root and quality on the interactive Circle of Fifths. See the original chord and its negative simultaneously, with voice-leading automatically applied. BUILD PROGRESSIONS Add chords to a progression and play them back — originals or negatives — with smooth voice leading between every chord. Common tones are held, not re-attacked. UNDERSTAND THE THEORY Built-in theory section explains the concept from first principles: the axis, the transformation formula, voice leading, and the history from Hugo Riemann to Jacob Collier. 5 SOUNDS Choose from Rhodes, Strings, Choir, Organ, or Synth Pad — the same high-quality soundfont used by professional music apps. MULTILINGUAL Full support for English, Spanish, French, German, Italian, and Portuguese.

MultiComb turns a bank of moving comb filters into a playable sound-design effect. Four independent comb voices create shifting resonances across the stereo field, each moving with its own timing, spacing, and character. Smooth modulation keeps the bank alive while Bite introduces stepped sample-and-hold disturbances that push individual combs into new resonant relationships. The result can move from hollow coloration and subtle animation to metallic ringing, mechanical movement, fractured resonance, and unstable tonal textures. MultiComb works across drums, vocals, pads, guitars, percussion, and full electronic textures—but it especially comes alive on leads, basslines, arpeggios, plucks, and other short-note sequences. Individual notes excite the comb bank differently, turning simple melodic or rhythmic patterns into animated, resonant phrases. Teeth reshapes the fundamental comb structure. Motion keeps it moving. Spread pulls the voices apart. Feedback lets resonances ring. Color moves from dark and hollow toward bright, steel-like character. And then there’s Bite. Bite introduces independent stepped disturbances across the comb bank. At restrained settings it adds little irregular catches and tonal shifts. Push it harder and the resonances begin snapping into fractured, metallic relationships of their own. Seven controls. Four combs. Lots of teeth.
