Yes. ChatGPT can help write music as editable MIDI when connected to Aether, a MIDI LLM plugin: you prompt, generate, then drag the result into your music workflow. That gives you musical note data to edit, rather than establishing that ChatGPT by itself creates a finished audio recording. Aether can connect to ChatGPT with your own API key, or use a local model through Ollama or LM Studio. The plugin itself is available as AU, VST3, and a standalone app for macOS and Windows.
What “Write Music” Means Here
For a developer or technical creator, the useful distinction is between composing musical instructions and producing a finished track. MIDI represents notes and their timing; a sound comes from playing those notes through an instrument. Aether’s stated workflow is prompt, generate, drag, and its output is MIDI. That can give you a starting part you can inspect and revise, but the available information does not establish that ChatGPT supplies a finished mix, a particular instrument sound, or an audio file.
A MIDI result is useful when your goal is to build a melody, drum pattern, or other part inside a project and retain control over its notes. It is less conclusive if your goal is a ready-to-publish song with vocals, arrangement, mixing, or a particular production style: those capabilities are not established here. Treat any generated part as draft material until you have listened to it in your chosen instrument and checked whether it fits the rest of your music.
How ChatGPT Fits Into The Workflow
Aether is described as a MIDI LLM plugin that you load like another instrument. It can connect to ChatGPT, Claude, Gemini, Grok, DeepSeek, OpenRouter, or Hugging Face using your own API key; it can also run a local model through Ollama or LM Studio. No forced subscription is stated. The available facts do not specify API costs, model requirements, or how to configure a particular provider, so check Aether’s site and the provider’s current instructions before setting up a connection.

- Choose a musical goal. Decide what part you need: for example, a short melody, a repeating bass idea, or a drum part. Give it a role in the arrangement instead of asking for an entire finished song.
- Describe constraints in plain language. Specify the intended mood, how busy the part should feel, and what it should leave room for. If you know a key, tempo, meter, or note range, include it as a constraint; do not assume the model or plugin will interpret every technical term exactly as you intend.
- Prompt through Aether. Connect ChatGPT using your own API key, then use the plugin’s prompt-and-generate workflow. The exact setup steps and supported prompt syntax are not established here; consult the vendor’s instructions for those details.
- Drag the MIDI into your work. Listen to the part with the instrument and surrounding material you intend to use. Check the notes and timing, then edit anything that clashes with your musical direction.
- Iterate with one change at a time. If the result is too busy, ask for a simpler part; if it competes with another layer, describe the space that layer needs. Changing one constraint per prompt makes it easier to tell whether the new result addresses the problem.
Prompt Examples For A First Draft
These examples are starting points for describing musical intent, not claims about special ChatGPT commands or guaranteed outputs. Adjust them to the piece you are making, and verify the generated MIDI by listening and editing.
- Melody: “Write a short, memorable lead melody that leaves clear pauses between phrases. Keep the movement restrained and leave room for a vocal line.”
- Bass: “Create a steady bass part that supports the harmony without drawing attention away from the lead. Use a simple repeating idea, with a small variation at the end.”
- Drums: “Make a restrained drum pattern for a verse. Keep the pulse clear, leave space in the middle of the arrangement, and add a modest change to signal the transition into the next section.”
- Revision: “Simplify this part: reduce its note density, preserve its general character, and leave more space for the other layers.”
When musical precision matters, add the information you already know, such as the key or meter, and check whether the generated notes actually follow it. Do not rely on a text description alone to guarantee exact note choices, timing, structure, or compatibility with a particular project. Those details are not established by the available product information.

What To Check Before Relying On It
- Your setup: Aether is stated to install as AU, VST3, and standalone software for macOS and Windows. Check the vendor’s current requirements and whether your own host supports the format you plan to use; no particular DAW compatibility list is established here.
- The musical specifics: Support for a particular genre, instrument, tempo, meter, key, song form, or level of MIDI detail is not established. Try a small prompt and inspect the result before building a larger arrangement around it.
- The model connection: Aether supports connecting AI services with your own API key and running local models through Ollama or LM Studio, but model access, setup, and any associated costs are not specified. Check the relevant vendor sites for those particulars.
- Rights and consent: If your project involves someone’s voice, a cover, or samples, obtain the relevant consent and check Aether’s and the model provider’s terms for your intended use. The available facts do not establish licensing permissions or commercial-use rights.
When This Approach Makes Sense
This workflow is most directly suited to someone who wants a prompt-based way to create editable MIDI material and is willing to shape the result afterward. It is a practical route to a first musical idea when you can judge notes in context and revise them. If you need finished audio, a specific genre result, a named instrument, or confirmed rights for a release, those needs are not established by the available facts. Check the relevant vendor terms and product details before depending on them.
