Aether + Cubase

AI MIDI Generator for Cubase

Load Aether as a VST3 instrument, describe the part you hear, and drag the MIDI into your Cubase project.

Aether is an AI MIDI generator built for the Cubase workflow. Add it as a VST3 instrument on an instrument track, describe the part you want in plain language, and drag the generated MIDI into your project — standard, editable notes that behave like anything you recorded into the Key Editor yourself.

Loading Aether in Cubase

Aether installs as a VST3 on Windows and macOS — Steinberg's own plugin format, so Cubase (and Nuendo) pick it up natively in the plugin manager. Add it to an instrument track and start prompting, or sketch ideas in the standalone app without opening Cubase at all.

From prompt to the Key Editor

Everything Aether writes is standard MIDI. Drag a generated part onto a track and refine it in the Key Editor, or keep iterating in chat — Aether edits the part it already wrote instead of starting over.

  • ✓Generate separable Bass, Harmony, and Lead parts on their own MIDI channels
  • ✓Lock to Host syncs BPM and time signature from the Cubase transport
  • ✓Multi-track .mid export with tempo and time signature embedded

Frequently asked questions

Does Aether work with Cubase?

Yes. Aether loads in Cubase as a VST3 instrument on Windows and macOS. Add it to an instrument track, prompt for a part, and drag the generated MIDI into your project.

Does it work in Nuendo too?

Yes — Nuendo hosts the same VST3 plugins as Cubase, so Aether loads the same way.

Can Aether follow my project tempo?

Yes. Lock to Host syncs BPM and time signature from Cubase's transport, and exported .mid files carry tempo and time signature.

Do I need a subscription?

No. Aether is a one-time $60 purchase. Bring your own AI provider key or run a local model through Ollama or LM Studio for free.
