AI MIDI Plugin
AI MIDI Plugin for Your DAW
Aether is an AI MIDI plugin that turns plain-language prompts into playable, drag-to-DAW MIDI, without leaving your session.
Aether by Umbral Audio is an AI MIDI generator plugin for macOS and Windows (AU, VST3, Standalone). Describe a part in plain language; it plans, generates, and refines editable MIDI in named layers you drag into your DAW. $60 one-time, lifetime 1.x updates, up to 3 machines, no plugin subscription required. Prompts can be written in your own language, and Aether replies in it.
Drums land on their own channel and stay editable MIDI, same as every other layer.
Aether by Umbral Audio is an AI MIDI plugin you load like any other instrument. Open it on a track, describe the part you want, and it generates editable MIDI you can drag into your project. It runs as VST3, AU, and Standalone, so it fits whatever DAW you already produce in.
Every format, every major DAW
Aether installs as an AU, VST3, and Standalone app for macOS and Windows, so it runs inside Ableton Live, FL Studio, Logic Pro, Cubase, Fender Studio Pro (formerly Studio One), Bitwig, and Reaper, or on its own without a DAW.
Generate, then refine in chat
Prompt Aether for a melody, chord progression, bassline, or a full layered arrangement, then keep talking to it. It refines the MIDI it already wrote, and new parts land as named layers alongside the old ones, so you iterate toward the arrangement instead of rerolling from scratch.
Producer tools built in
Aether is more than a prompt box. It includes a piano roll, a MIDI Library that groups each idea with its version history, post-processing, MIDI capture, and custom prompts you can reuse.
- ✓Any number of named, instrument-tagged layers with per-layer solo and mute
- ✓Multi-track .mid export with one named track per layer, tempo, and time signature
- ✓Drag-to-DAW MIDI on any track
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.
