| Description: | Demo: https://vimeo.com/1188434525 Oedipa is a MIDI effect that walks a Tonnetz — the 2D triangular lattice of triads connected by neo-Riemannian transforms (P / L / R) — and emits the chords it finds. Instead of writing a chord progression, you write a short cyclic program of P / L / R / hold / rest operations and let the walker turn it into harmony. What you control: - Start chord — click a triangle on the lattice or play notes into the device. - Cell program — a short cyclic array of 1–8 cells. Each cell carries an op plus per-cell velocity, gate, probability, and timing. The default [P, L, R, hold] walks C → Cm → A♭ → Fm → F → Am → C over 8 cells — chromatic mediants and mode mixture, the territory NR transforms make easy. - Jitter + seed — per-step probability of replacing the cell's op with a uniform-random one. Reproducible from the seed. 0 = strict program; 1 = random walk on the lattice. - Rate — cell length in 16th-note steps (1–64; default 4 = 1 quarter note). Small values = arpeggio territory; larger values = long-form pad / drift. - Voicing — close / spread / drop2, with optional 7th extension. - Rhythm + motion — rhythm preset (legato / onbeat / offbeat / syncopated / all / turing), arp mode, step direction (forward / reverse / pingpong / random), and a Turing-machine random source for live-steered variation. Deterministic. For a fixed configuration the walk is reproducible — scrubbing the transport or restarting playback produces the same MIDI bit-for-bit. Every cell field is independently host-automatable; the program is meant to be steered live rather than re-edited. Steering philosophy inspired by Ornament & Crime's Automatonnetz — a small repeating program steered live, rather than a long-form sequence. Mechanics differ (4 cells of P/L/R/hold/rest with per-cell expression, vs. a 5×5 chord grid); the design intent is shared. Requires: Live 12, Max 8.6+ (Max for Live). Free under MIT.
