MIDI Agent review
A desktop MIDI generator with prompt-based parts and multiple AI access options.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
MIDI Agent is an AI-assisted MIDI generator for producers, composers, and beatmakers who want to create or edit musical parts from prompts. It can generate chord progressions, melodies, drum patterns, and basslines, with controls for elements such as key, scale, length, and genre. Chord generation also includes voicing and feel controls. The software is available as VST3, AU, and AAX plugins, as well as a standalone app for Windows and macOS. It suits desktop workflows that benefit from prompt-led MIDI creation, though it is not a fit for mobile production.
Its model access is a central part of the product’s appeal: users can connect accounts, supply API keys, or work with local models through Ollama or LM Studio. Listed integrations and model providers include ChatGPT, OpenAI, Anthropic, DeepSeek, Gemini, and OpenRouter. Generated MIDI can be saved or dragged into a DAW; existing MIDI can also be extended or varied, and audio recordings can be transcribed to MIDI. This range goes beyond chord generation, so MIDI Agent may be useful when a workflow spans several kinds of musical parts. Buyers who want a focused chord tool without model setup may find the multiple access routes less relevant.
According to the vendor’s pricing page, the MIDI Agent Plugin is a $99 one-time purchase and includes lifetime updates. MIDI Agent Pro adds managed AI model access and 500 AI generations per month for $20 per month, but requires a plugin license. The Pro subscription is therefore an additional cost rather than a standalone entry point. The published plans make most sense for buyers who value managed model access or expect regular generation; users who prefer connected accounts, API keys, or local models can choose those routes instead. Choose MIDI Agent for its mix of MIDI generation, editing, transcription, and model options; consider another tool if you need mobile access or a free plan.
