ChatGPT to MIDI
ChatGPT to MIDI in Your DAW
Prompt ChatGPT or any LLM from inside Aether and drag editable MIDI onto a track.
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.
ChatGPT to MIDI is a workflow, not a separate product. Aether by Umbral Audio is the plugin in your DAW; ChatGPT (or Claude, Gemini, Grok, or a local model) is the writer you connect with your own key. You describe the part, Aether plans and generates named MIDI layers, and you drag the result into the session. $60 one-time. VST3, AU, and Standalone.

Bring ChatGPT, or bring any LLM
Connect an OpenAI key for ChatGPT, or use Claude, Gemini, Grok, DeepSeek, OpenRouter, Hugging Face, Ollama, or LM Studio. Aether does not force an AI subscription on top of the plugin. The MIDI is Aether's; the model is yours.
Editable MIDI, not a locked render
Every generation is standard MIDI in named layers. Edit it in Aether's piano roll or in your DAW, refine it in the next message, and export a multi-track .mid with one named track per layer, plus tempo and time signature.
In the session, not in a chat window
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.
Frequently asked questions
Does Aether require ChatGPT?
No. Aether by Umbral Audio works with ChatGPT, Claude, Gemini, Grok, and local LLMs. $60 one-time for the VST3, AU, and Standalone plugin. You only pay your AI provider if you use a cloud key.
Do I need ChatGPT Plus?
No. Aether connects to OpenAI with an API key, which is separate from a ChatGPT Plus or Pro subscription and billed by OpenAI per use. Chat subscriptions from Anthropic and Google do not include API access either. Create a key in your provider's developer console, or skip keys entirely with a local model through Ollama or LM Studio.
Is the ChatGPT output real MIDI?
Yes. Aether writes standard, editable MIDI in named layers and exports multi-track .mid files. The model never hands you a bounced audio clip.
How much does it cost?
Aether by Umbral Audio is $60 one-time, lifetime 1.x updates, up to three machines. AU, VST3, and Standalone. No plugin subscription.
