Performance RNN - PyTorch

PyTorch implementation of Performance RNN, inspired by Ian Simon and Sageev Oore. "Performance RNN: Generating Music with Expressive Timing and Dynamics." Magenta Blog, 2017. https://magenta.tensorflow.org/performance-rnn.

This model is not implemented in the official way!

Generated Samples

• A sample on C Major Scale [MIDI, MP3]
  • control option: -c '1,0,1,0,1,1,0,1,0,1,0,1;4'
• A sample on C Minor Scale [MIDI, MP3]
  • control option: -c '1,0,1,1,0,1,0,1,1,0,0,1;4'
• A sample on C Major Pentatonic Scale [MIDI, MP3]
  • control option: -c '5,0,4,0,4,1,0,5,0,4,0,1;3'
• A sample on C Minor Pentatonic Scale [MIDI, MP3]
  • control option: -c '5,0,1,4,0,4,0,5,1,0,4,0;3'

Instructions

• Download datasets

  cd dataset/
  bash scripts/NAME_scraper.sh midi/NAME

• Preprocessing

  # Preprocess all MIDI files under dataset/midi/NAME
  python3 preprocess.py dataset/midi/NAME dataset/processed/NAME

• Training

  # Train on .data files in dataset/processed/MYDATA, and save to save/myModel.sess every 10s
  python3 train.py -s save/myModel.sess -d dataset/processed/MYDATA -i 10
  
  # Or...
  python3 train.py -s save/myModel.sess -d dataset/processed/MYDATA -p hidden_dim=1024
  python3 train.py -s save/myModel.sess -d dataset/processed/MYDATA -b 128 -c 0.3
  python3 train.py -s save/myModel.sess -d dataset/processed/MYDATA -w 100 -S 10

  

• Generating

  # Generate with control sequence from test.data and model from save/test.sess
  python3 generate.py -s save/test.sess -c test.data
  
  # Generate with pitch histogram and note density (C major scale)
  python3 generate.py -s save/test.sess -l 1000 -c '1,0,1,0,1,1,0,1,0,1,0,1;3'
  
  # Or...
  python3 generate.py -s save/test.sess -l 1000 -c ';3' # uniform pitch histogram
  python3 generate.py -s save/test.sess -l 1000 # no control
  
  # Use control sequence from processed data
  python3 generate.py -s save/test.sess -c dataset/processed/some/processed.data
