Smart Voice Leading
Finds the smoothest transition between chords, with tension and style controls to dial in the colour.
Timeline Arranger
Drag chord blocks onto a timeline. Set per-chord patterns — arpeggio, strum, block — and reshape on the fly.
AUv3 Plugin
Drops into Logic Pro, AUM, and any AUv3 host as a MIDI FX, with full host transport and automation.
Standalone Mode
Internal clock plus a CoreMIDI virtual port routes notes to any external synth or hardware instrument.
MIDI Export
Deterministic .mid files for sharing sketches or pulling them into any DAW for further production.
Humanize & Swing
Per-chord swing and humanization controls keep generated parts feeling alive, never robotic.
Practical Theory
Pop and jazz harmonic vocabulary at the core — extensible later with reharmonization packs.
Privacy
Local sketches stored as JSON. No cloud sync to manage.
No telemetry, no accounts, no network calls home. The app doesn't know who you are or what you write.
