MuseGAN

MuseGAN is a project on music generation. In a nutshell, we aim to generate polyphonic music of multiple tracks (instruments). The proposed models are able to generate music either from scratch, or by accompanying a track given a priori by the user.

We train the model with training data collected from Lakh Pianoroll Dataset to generate pop song phrases consisting of bass, drums, guitar, piano and strings tracks.

Sample results are available here.

Prerequisites

Below we assume the working directory is the repository root.

Install dependencies

• Using pipenv (recommended)

  Make sure pipenv is installed. (If not, simply run pip install pipenv.)

  # Install the dependencies
  pipenv install
  # Activate the virtual environment
  pipenv shell

• Using pip

  # Install the dependencies
  pip install -r requirements.txt

Prepare training data

The training data is collected from Lakh Pianoroll Dataset (LPD), a new multitrack pianoroll dataset.

# Download the training data
./scripts/download_data.sh
# Store the training data to shared memory
./scripts/process_data.sh

You can also download the training data manually (train_x_lpd_5_phr.npz).

Scripts

We provide several shell scripts for easy managing the experiments. (See here for a detailed documentation.)

Below we assume the working directory is the repository root.

Train a new model

1. Run the following command to set up a new experiment with default settings.

   # Set up a new experiment
   ./scripts/setup_exp.sh "./exp/my_experiment/" "Some notes on my experiment"

2. Modify the configuration and model parameter files for experimental settings.

3. You can either train the model:

   # Train the model
   ./scripts/run_train.sh "./exp/my_experiment/" "0"

   or run the experiment (training + inference + interpolation):

   # Run the experiment
   ./scripts/run_exp.sh "./exp/my_experiment/" "0"

Use pretrained models

1. Download pretrained models

   # Download the pretrained models
   ./scripts/download_pretrained_models.sh

   You can also download the pretrained models manually (pretrained_models.tar.gz).

2. You can either perform inference from a trained model:

   # Run inference from a pretrained model
   ./scripts/run_inference.sh "./exp/default/" "0"

   or perform interpolation from a trained model:

   # Run interpolation from a pretrained model
   ./scripts/run_interpolation.sh "./exp/default/" "0"

Sample Results

Some sample results can be found in ./exp/ directory. More samples can be downloaded from the following links.

• sample_results.tar.gz (54.7 MB): sample inference and interpolation results
• training_samples.tar.gz (18.7 MB): sample generated results at different steps
