midiGPT

Generate deep minimal house basslines powered by the latest OpenAI models.

Prerequisites

1. Python 3.9+
2. Create and activate a virtual environment (optional but recommended)
3. Install dependencies:

pip install -r requirements.txt

Streamlit Web App

streamlit run app.py

Enter your OpenAI API key in the sidebar, provide a creative prompt, and click Generate MIDI.
The app will stream the model output, convert it into a .mid file, and render a piano-roll preview. You can download the MIDI directly from the interface.

CLI Usage

export OPENAI_API_KEY="sk-..."

python cli.py "Funky minimal-house bassline in A minor with syncopated groove" \
              --output my_bassline.mid \
              --model gpt-4.1

The script will save my_bassline.mid in the current directory.
