About MIDI Agent

MIDI Agent is an AI-powered VST3/AU plugin designed for music producers, composers, and film scorers who need to generate and edit MIDI directly within their digital audio workstation using natural-language prompts. The tool converts text into original melodies, harmonies, rhythms, chord progressions, and longer compositions with adjustable parameters for key, scale, length, and complexity, and can synchronize output to the project tempo. It also offers MIDI continuation and expansion to create coherent variations from existing clips, as well as audio-to-MIDI transcription by importing audio files and converting them into editable MIDI data. Users can bring their own AI models through integrations with providers like OpenAI, Anthropic, Google, DeepSeek, and others, either via their own API keys or managed access. The plugin supports major DAWs including Ableton Live, FL Studio, Logic Pro, Cubase, Studio One, Reaper, Bitwig Studio, and GarageBand, with AAX support for Pro Tools listed as coming soon. It is available as a one-time purchase with an optional Pro subscription for additional features, making it suitable for workflows that require flexible, prompt-driven MIDI creation and editing without leaving the DAW environment.
