Generates multitrack MIDI music with a language model trained on 8-bar pieces. Runs in the browser as a Docker app, for musicians and developers who want to try AI-made MIDI. Multitrack Midi Music Generator is a kit in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Download it on this page, a zip of its files. Nothing in it runs by itself. Made by juancopi81 ## About ### What it is Multitrack Midi Music Generator makes music as MIDI, with several tracks at once. It uses two models named in the Space, a tokenizer and a language model whose names mention 8 bars. The Space runs on Hugging Face, so you can try it in a browser with nothing to install. ### Who it suits Musicians and hobbyists who want AI-made MIDI to play with, and developers who want to study a small Python music app packaged in Docker. | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Music | Composers and hobbyists | Generate MIDI pieces as starting ideas | Create a piece and open it in a music editor | | Games | Indie developers | Get quick musical sketches to try in a project | Generate a short piece and test it in a prototype | | Machine learning | Researchers | Look at how a tokenizer and language model make music | Read model.py and the tokenizer files | | Software | Developers | Build and run the Docker image locally | Run the container and publish port 7860 | Anyone who needs finished audio recordings rather than MIDI can skip it. ### Where to use it It runs in these places. - A web browser, on the Space's page at Hugging Face - Windows, with Docker - macOS, with Docker - Linux, with Docker | Use case | Who | What they get back | | --- | --- | --- | | Generate a multitrack piece | Musicians | A MIDI piece with several tracks | | Collect ideas for a project | Game and video makers | Short musical sketches in MIDI form | | Study the code | Developers | A local copy with main.py and model.py to read | ### How to set it up Using the Space online needs only a browser. A copy on your own computer needs the following. - Docker - Python and pip, for the huggingface\_hub package that gives you the hf command - Disk space for the repository, which holds 11 files 1. Install the huggingface\_hub package. 2. Download the Space's files into a local folder. 3. Move into that folder. 4. Build the Docker image and name it multitrack-midi-music-generator. 5. Run the container with port 7860 published to your computer. ```sh pip install -U huggingface_hub hf download juancopi81/multitrack-midi-music-generator --repo-type space --local-dir multitrack-midi-music-generator cd multitrack-midi-music-generator docker build -t multitrack-midi-music-generator . docker run -it -p 7860:7860 multitrack-midi-music-generator ``` ### How to use it Open the Space's page on Hugging Face, or start the container and open your browser on port 7860 of your computer. Then ask it to generate a piece and listen to or download the result. ```sh docker run -it -p 7860:7860 multitrack-midi-music-generator ``` | Tool | What it does | | --- | --- | | main.py | The main file of the app | | model.py | Holds the code that works with the music model | | string\_to\_notes.py | Converts the model's text output into notes | | docker build | Builds the image from the Dockerfile | | docker run | Starts the container and publishes port 7860 | ### Example You start the container, open the page on port 7860 and generate a piece. You get back a multitrack MIDI result that you can open in a MIDI editor or player. ### For newcomers and experts MIDI is a file of notes and timing, not recorded sound, so any music program can play it with the instrument you pick. The first small thing to try is the online Space, with one generated piece. The model names point to a tokenizer for 8-bar pieces and a language model trained for 40 epochs. The model writes music as text tokens, and a helper turns them into notes. The repository splits this across constants.py, model.py, utils.py and string\_to\_notes.py. You ask for a piece → The language model writes music tokens → string\_to\_notes.py turns them into notes → The page returns a multitrack MIDI piece ### Good to know The Space states no usage limits, so treat it as a demo you can read and adapt. - License: mit - Cost to run: none named - Data it reaches: the Space files and the two model files that Hugging Face supplies - Hardware: the Space is set to cpu-basic at Hugging Face, and what your own computer needs is not stated ## README ````markdown # Multitrack Midi Music Generator Generates multitrack MIDI music with a language model trained on 8-bar pieces.
