Aether

Aether is an AI co-producer that lives on a track in your session. Instead of clicking every note into a piano roll, you tell it what you want, "a dark, driving minor-key bassline at 124 BPM," or "a warm lo-fi chord progression in F minor," and it plans the part, generates the MIDI, and hands you notes you can drag straight onto a track.

Aether reasons about key, scale, voice leading, and rhythm, so the parts it writes sit in your track instead of fighting it. Don't like something? Ask for a change in the next message and it refines the MIDI it already wrote rather than starting over, so you iterate toward the idea in your head.

Generate separable Bass, Harmony, and Lead parts on their own MIDI channels, solo or mute any of them, capture and reload earlier takes from the built-in MIDI Library, clean things up in the piano roll, and export multi-track MIDI with tempo and time signature intact. Everything Aether produces is standard, editable MIDI.

Aether is bring-your-own-AI. Connect the model you already pay for with your own API key, or run a model locally and generate offline. You own the plugin outright for a one-time price, with no forced subscription.

Key features:

• Text-to-MIDI: generate melodies, chord progressions, basslines, and full multi-track ideas from natural-language prompts.
• Conversational refinement: follow-up messages edit the MIDI it already wrote.
• Music-theory-aware phrasing (key, scale, voice leading, rhythm).
• Separable Bass, Harmony, and Lead parts with per-part solo, mute, and MIDI channels.
• Drag-to-DAW MIDI and multi-track .mid export with tempo and time signature.
• MIDI Library with idea and version history.
• Built-in piano roll, post-processing, MIDI capture, and reusable custom prompts.
