Fishtail

Buy now — special introductory price for 4 weeks. Compose complete pieces, not loops. Music-theory algorithms—not generative AI. Seven musical channels.

Fishtail is a generative MIDI instrument for iPhone and iPad. It composes complete musical forms, then lets you shape, perform, retain and rearrange them!

Fishtail does not use AI to generate music. Its musical output is created through algorhythmic generation grounded in musical theory.

Build pieces from sections with independent keys, modes, meters, cadences and expressive treatments. Generate distinct Takes, compare them, reorder them and hand the next Take over at a natural whole-piece boundary.

Fishtail produces MIDI rather than sound. Use it standalone or as an AUv3 MIDI plug-in, and route its seven musical channels to the instruments you choose. Ableton Link supports shared tempo and transport.

Features: • Complete multi-section generative compositions • Seven-channel MIDI output • Retain, reorder and perform Takes • Seven intonation systems • Normal MIDI, pitch-bend and MPE output • MTS output • Ableton Link • .fishtail project save and recall • Standard MIDI and per-channel export • Experimental analogue CV file packages • Accessible light and dark interfaces
