Representation Learning for Drum Loops with Neural Networks
Support for a paper submitted to the Springer book Artificial Intelligence in Arts, Music and Design.
To use this, you need to install a Python MIDI library as follows: pip install git+https://github.com/jmmcd/python-midi/.
Also Keras/Tensorflow, Kivy, PyGame:
pip install kivy
pip install pygame
pip install --upgrade pip
pip install tensorflow
Then you need a MIDI drum-loop library for training data. I used a library from Groove Monkee. They have a cut-down version available for free which works. Start by pre-processing it (where <directory> contains the library, and this will write out images of the MIDI files plus one large numpy file):
python midi2numpy.py convert_lib <directory>
Then you can run the neural network, eg:
python vae_conv_keras_drums.py --latent_dim 2 --loss BCE --Lambda 0.010000 --dropout_rate 0.000000 --conv_layers 2 --filter_expansion 1 --kernel_size0 3 --kernel_size1 3
Some examples of the trained NN being used in a GUI:
Support for a previous, related paper presented at CSMC 2018 is in the CSMC_2018 directory.
