Strange Loop vs RollTab

Strange Loop writes its own music. Three coupled Lorenz attractors drive the piece — one proposes pitch, one shapes rhythm, one wanders the emotional plane. A Markov policy then decides what actually plays, learning from its own output and rewarding intervals that sound consonant. Chaos proposes, the policy disposes. Slide BLEND to choose who wins. Nothing is pre-recorded and nothing loops. Every run is new. PAINT ON THE MATHS Both scopes are paintable. Draw on the attractor and the trajectory bends toward what you drew and lingers there, pulling the melody into those pitches. Draw on the mood pad and the feeling follows your strokes — brightening the harmony, lifting the register, pushing the tempo. Set how hard the ink leans, how big the brush is, and how long it lasts before it fades. WHAT YOU GET • 26 scales — major and minor modes, pentatonics, blues, whole tone, harmonic and melodic minor, altered, both octatonics, and folk scales from Japan, China, Egypt, Spain, Arabia and Hungary • 7 accompaniment styles — chaos grooves, jazz comping with walking bass, stride piano, Alberti bass, classical, arpeggios, ambient rolls • A sampled grand piano plus synthesised voices: soft piano, glass, strings, FM bell, AM organ, pluck, fat saw and more • 6 moods on a valence/arousal plane, from serene to tense, driving chord quality, register, tempo and note length • Live scopes — the attractors, the note-probability distribution the engine is sampling from, and the mood point, all drawn in real time • Deep control: key, scale, tempo, chaos rho, rhythm spread, grace notes, chord-tone pull, softmax temperature, per-track mixer • Record a take and export it as a standard MIDI file to the Files app — melody, chords and bass on separate tracks TWO AUDIO UNITS Strange Loop ships as an instrument AUv3 and as a MIDI processor AUv3, so it can either play its own sounds or sequence any other instrument in your host. Melody, chords and bass each send on their own MIDI channel, so one instance can drive three different instruments. Both Audio Units follow your host's transport and tempo — hit play in AUM, GarageBand, Logic, Cubasis or Zenbeats and it locks to the grid. One install registers both.
