WAIL - Industrial Feedback Synthesiser, Drone and AUV3 FX Turn unstable feedback into a playable instrument. WAIL forces a self-resonating signal into submission, generating harsh drones, soaring screams, and aggressive textures that traditional synths refuse to touch. Built for zero menu-diving and pure performance, WAIL delivers raw, uncompromised noise control in a single intuitive screen. TAME THE NOISE: 4 Dynamic XY Pads: Instant tactile control over Feedback/Filter, Bite/Space, Ring/Fold, and Comb/Sub. Dedicated Performance Knobs: Master, Spread, Grind, and Tune, with dual-axis Coarse/Fine tuning designed for precise, subtle adjustments mid-performance. Real-Time Visuals: Built-in integrated oscilloscope displays waveform stability and feedback saturation as you play. Drone or MIDI Triggered: Play as an evolving drone, or connect a MIDI keyboard or sequencer. AUv3 FX: Load WAIL as an effect in your host and run any track through its feedback engine. Push a drum loop, a vocal, or a synth line into full self-resonating collapse, or layer WAIL's own drone on top of what you send in. Seamless AUv3 Integration: Full host transport sync, preset save/recall, and universal MIDI CC learn across all 12 parameters. Universal Support: Formatted natively for both iPad and iPhone as an AUv3 plugin or Standalone app. 12 parameters. 4 XY pads. One feedback loop trying to escape.

Strange Loop
This app generates unique, non-repeating music using chaos theory and AI. Users can influence the composition by painting on mathematical attractors and mood pads, choosing from various scales, accompaniment styles, and synthesized sounds. It also functions as an AUv3 instrument and MIDI processor.
- AI-generated, non-repeating music
- Interactive painting on attractors and mood pads
- 26 scales and 7 accompaniment styles
- Sampled grand piano and synthesized voices
- AUv3 instrument and MIDI processor
- MIDI file export

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.
