Enter a prompt and it generates multi-track MIDI arrangements (chords, bass, drums). It features a full in-browser Piano Roll for editing, playback, and direct MIDI export to your DAW.\n\nBeatFlow is not an MP3 generator. It utilizes the LLM as a Music Director capable of genuine music theory reasoning. Instead of predicting waveforms, the LLM architects a complete musical structure—planning sections, energy curves, and harmonic progressions—before composing. The output is a fully editable, structurally coherent MIDI arrangement.\n\n\n- Includes a fully functional web-based Piano Roll editor.\n- Export standard MIDI files to drop directly into Ableton Live, FL Studio, or Logic Pro.\n- Uses LLMs to understand music theory, generating structured sections (Intro, Groove, Breakdown) rather than random notes.\n\n## Quick Deployment\n\nThe project is split into a Frontend (Next.js) and Backend (FastAPI).\n\n- Python 3.10+\n- Node.js 18+ (pnpm recommended)\n\n### Backend Setup (Python/FastAPI)\n\n```bash\ncd beatflow\npip install -r requirements.txt\n```\n\nConfigure Environment:\n\nCreate a `.env` file and add:\n\n```text\nOPENROUTER_API_KEY=your_key\nLLM_BASE_URL=https://openrouter.ai/api/v1 # (or other OpenAI-compatible endpoint)\nLLM_MODEL=your_model_name # (e.g., gpt-4o, gemini-3-pro)\n\n# Optional proxy settings\nHTTP_PROXY=\nHTTPS_PROXY=\n```\n\nStart server:\n\n```bash\npython main.py\n```\n\n### Frontend Setup (Next.js)\n\n```bash\ncd frontend\npnpm install\npnpm dev\n```\n\nOpen `http://localhost:3000` to start creating.\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fthe0cp%2Fbeatflow","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fthe0cp%2Fbeatflow","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fthe0cp%2Fbeatflow/lists"}
