This repository allows you to train GPT-2 on the Johann Sebastian Bach chorale dataset. You can train both MMMTrack and MMMBar from the paper.

Requirements:

pip install transformers
pip install tokenizers
pip install torch
pip install music21
pip install note_seq

Training:

1. Clone this repository git clone https://github.com/AI-Guru/MMM-JSB.git.
2. Train MMMTrack with python train_jsb_mmmtrack.py.
3. Train MMMBar with python train_jsb_mmmbar.py.

Sampling: Run the jupyter notebook.

Training should take roughly one hour on a GPU per model for the JSB dataset.

A pretrained network can be found here: https://ai-guru.s3.eu-central-1.amazonaws.com/mmm-jsb/mmm_jsb_checkpoints.zip

• TensorFlow support is rudimentary.
• Data preprocessing and training on the Lakh dataset.
• Implementation as a tool or a DAW plugin.
