Our verdict on Aether
Aether is a desktop AI MIDI generator for macOS and Windows from Umbral Audio, LLC. It runs as AU, VST3, or standalone software, turning natural-language prompts into editable chord, bassline, melody, arrangement, and drum parts. Producers can specify key, scale, genre, mood, BPM, time signature, and sections, then refine results through multi-turn chat. Named, instrument-tagged layers provide per-layer solo and mute controls, while standard multi-track MIDI export suits users who want generated ideas they can continue editing in a DAW.
The published plan is a single Aether license at $60 USD as a one-time payment, with activation on up to three machines. It includes unlimited generations, all supported AI providers, local model support through Ollama and LM Studio, a MIDI library with full history, smart post-processing, piano roll, and playback. Cloud AI usage is billed separately by the connected provider; local Ollama or LM Studio models can run without provider API charges. Refunds are generally limited to verified defects reported within 14 days, with statutory EU/EEA/UK withdrawal terms before download or activation.
Its ecosystem is aimed at a computer-based production workflow. Aether supports Ableton Live, FL Studio, Logic Pro, Cubase, Studio One, Bitwig, and Reaper, with DAW drag-and-drop and host-tempo synchronization. Chat connections include ChatGPT, Claude, Gemini, Grok, DeepSeek, OpenRouter, and Hugging Face. The MIDI library adds search, tags, version history, and live capture, giving repeated ideas a place to be organized. Choose Aether if you want conversational control over multiple editable tracks and can manage AI-provider access. Consider another option if you need a browser or mobile workflow, a free entry tier, or bundled cloud-generation costs.

Extremely disappointing — $60 wasted on unreliable AI-generated MIDI
Extremely disappointing — £60 wasted on unreliable AI-generated MIDI I bought Aether expecting a useful AI-powered music production tool that could generate MIDI from straightforward musical instructions. Unfortunately, my experience has been incredibly disappointing. I spent a considerable amount of time setting up the local AI model using Ollama, following the instructions and configuring the model to the recommended 32,768-token context length. Even after all that effort, the results were poor. I asked it to generate a simple four-bar chord progression, specifying the exact notes for each chord. It couldn’t even get that right. One chord contained the wrong note, changing the intended harmony entirely. When I tried asking it to correct that single chord, the result became worse. Repeating the original instructions produced further incorrect results. These weren’t complicated musical requests. They were basic, explicit instructions that I expected a product like this to follow reliably. What makes the experience even more frustrating is the additional cost involved in getting access to potentially better AI models. I paid $60 for the plugin, only to discover that using cloud-based AI involves separate API charges. In my view, these additional costs should be made much more prominent in the marketing, particularly when the quality of the included local-model experience is so disappointing. I understand that AI-generated music won’t always be perfect. However, there is a considerable difference between occasionally needing to edit a creative result and a tool repeatedly failing to follow precise instructions. I contacted Umbral Audio hoping for a satisfactory resolution, but my refund request was refused. The response was that AI output accuracy is not guaranteed and that dissatisfaction with generated results is not grounds for a refund. So I’m left with a $60 plugin that, in my experience, hasn’t delivered what I expected, after spending hours trying to make it work. My advice to anyone considering buying Aether: think very carefully before spending your money. Understand that the advertised plugin price is not necessarily the end of your costs, and don’t assume that explicit musical instructions will produce correct MIDI. I certainly wouldn’t buy it again.
Cons- Update process is frustrating, with broken or non-functional download links.
- Additional costs are not made sufficiently clear in the marketing material.
- MIDI generation is unreliable, even when given explicit chord instructions.
- Results were disappointing despite using a local AI model with the recommended context length.
- Overall, the performance and user experience fall well short of expectations for a paid plugin.
