Tritonet

Tritonet is a real-time harmonic navigation system that treats harmony as an automatable, elastic layer rather than fixed notes. Built on the Circle of Fifths, it lets a performer or producer reshape chords, scales, and voice-leading on the fly — remapping the harmonic content of any incoming MIDI without rewriting a single note. This frees MIDI from fixed pitch: the same performance can be bent into new keys, modes, and voicings live. Developed over a decade for Ableton Live, Tritonet turns music theory into a playable, controllable instrument.

Most MIDI tools treat pitch as fixed — once played, notes are locked. Tritonet inverts this: it separates a performance from its harmonic content, making harmony an automatable, real-time parameter. A previously recorded MIDI pattern becomes reusable, because the harmonic matrix beneath it can be reshaped on the fly — remapping keys, modes, chords, and voice-leading without editing a single note.

This enables an entirely new class of instruments: pattern-focused designs where the performer plays gestures while Tritonet dynamically drives the underlying harmony. Because that musical matrix shifts live under the player’s controls, the same instrument can produce endlessly varied, yet compositionally coherent, output.

In short, Tritonet turns harmony into a playable dimension — making MIDI elastic, patterns reusable, and coherent musical generation possible directly at the MIDI layer.

The most compelling use I have observed involves teaching a single concept: the relationship between tension and resolution. After grasping only this idea, a person with no formal training is typically able to begin directing harmony on their own within minutes — making coherent musical choices intuitively rather than through memorized rules. This suggests that Tritonet does not simply automate harmony, but externalizes its underlying logic in a form that can be understood and controlled directly, which I consider its most significant outcome.
