A.I. Duet

A piano that responds to you.

About

This experiment lets you make music through machine learning. A neural network was trained on many MIDI examples and it learned about musical concepts, building a map of notes and timings. You just play a few notes, and see how the neural net responds.

CREDITS

Built by Yotam Mann with friends on the Magenta and Creative Lab teams at Google. It uses TensorFlow, Tone.js and open-source tools from the Magenta project. Check out more at A.I. Experiments.

OVERVIEW

A.I. Duet is composed of two parts, the front-end which is in the static folder and the back-end which is in the server folder. The front-end client creates short MIDI files using the players's input which is sent to a Flask server. The server takes that MIDI input and "continues" it using Magenta and TensorFlow which is then returned back to the client.

INSTALLATION

A.I. Duet only works with Python 2.7. There are two basic ways of installing A.I. Duet: with Docker or without Docker.

If you already have a Python environment setup, install all of the server dependencies and start the server by typing the following in the terminal:

cd server
pip install -r requirements.txt

If this does not work, jump down to the Docker installation instructions, which will walk you through installing A.I. Duet within a Docker container.

If it did install tensorflow and magenta successfully, you can run the server by typing:

python server.py

Then to build and install the front-end Javascript code, first make sure you have Node.js 6 or above and webpack installed. And then install of the dependencies of the project and build the code by typing the following in the terminal:

cd static
npm install
webpack -p

You can now play with A.I. Duet at localhost:8080.

DOCKER

Docker is an open-source containerization software which simplifies installation across various OSes. It is the simplest method to build and install both the front-end and back-end components. Once you have Docker installed, you can just run:

$ sudo docker build -t ai-duet .
$ sudo docker run -t -p 8080:8080 ai-duet

You can now play with A.I. Duet at localhost:8080.

MIDI SUPPORT

The A.I. Duet supports MIDI keyboard input using Web Midi API and the WebMIDI library.

PIANO KEYBOARD

The piano can also be controlled from your computer keyboard thanks to Audiokeys. The center row of the keyboard is the white keys.
