BeatFlow: Text-to-MIDI generator that plans full song structure (github.com)

BeatFlow has launched an innovative text-to-MIDI generator that empowers users to create complete song structures with ease. By leveraging a language model (LLM), this tool goes beyond simple note generation to thoughtfully plan musical elements such as sections, energy curves, and harmonic progressions. Users can input prompts to receive multi-track MIDI arrangements that include chords, bass, and drums, all of which can be edited in a robust in-browser Piano Roll before being exported directly to popular Digital Audio Workstations (DAWs) like Ableton Live, FL Studio, or Logic Pro. Significantly, BeatFlow's ability to integrate music theory understanding into its generative process sets it apart from other AI music tools. This approach ensures that the output is not just a random assortment of notes, but a coherent and structured composition broken down into identifiable sections like Intro, Groove, and Breakdown. Built using modern technologies such as Next.js for the frontend and FastAPI for the backend, BeatFlow also supports seamless integration with the OpenRouter API, making it accessible and expandable for developers interested in enhancing music production with AI.
