Aether + Reaper
AI MIDI Generator for Reaper
Insert Aether as a VSTi on any track, describe the part you hear, and drag the MIDI into your project.
Aether is an AI MIDI generator that drops into Reaper like any other virtual instrument. Insert it on a track's FX chain, describe the part you want in plain language, and drag the generated MIDI into your project — standard items you can open in the MIDI editor and shape like anything you tracked yourself.
Loading Aether in Reaper
Aether installs as a VST3 on Windows and macOS (plus AU on macOS), so Reaper finds it on its next plugin scan. Insert it as a virtual instrument on any track, or run the standalone app when you don't need a project open.
From prompt to MIDI item
Everything Aether writes is standard MIDI. Drag a generated part onto a track as a MIDI item, then edit it in Reaper's MIDI editor — or keep refining in chat, where Aether edits the part it already wrote instead of rerolling.
