Loading Aether in Logic Pro

Aether installs as an Audio Unit (AU) on macOS, so Logic Pro validates and lists it with your other instruments. Instantiate it on a software instrument track and start prompting. There's also a standalone app for sketching ideas away from Logic.

From prompt to region

Each generation is standard MIDI you drag out of Aether and onto a track. Edit it in Logic's Piano Roll, layer it with your own playing, or send follow-up prompts and let Aether refine the part it already wrote.

  • ✓Compose in any number of named instrument layers, each with per-layer solo and mute
  • ✓Music-theory-aware phrasing that respects key, scale, and rhythm
  • ✓Multi-track .mid export with one named track per layer, tempo, and time signature

Prompt it in your own language

Name a genre or a drum style in French, German, Japanese, Korean, Chinese or most other languages and Aether routes it to the same musical guidance as the English name. It replies in the language you wrote in too, so the plan it hands back reads the way you asked. Coverage varies by language and genre; where a name is missing, the Genre and Style menus still get you there.
