I built deepjazz in 36 hours at a hackathon. It uses Keras & Theano, two deep learning libraries, to generate jazz music. Specifically, it builds a two-layer LSTM, learning from the given MIDI file. It uses deep learning, the AI tech that powers Google's AlphaGo and IBM's Watson, to make music -- something that's considered as deeply human.
Check out deepjazz's music on SoundCloud!
Run on CPU with command:
python generator.py [# of epochs]
Run on GPU with command:
THEANO_FLAGS=mode=FAST_RUN,device=gpu,floatX=float32 python generator.py [# of epochs]
Note: running Keras/Theano on GPU is formally supported for only NVIDIA cards (CUDA backend).
Note: preprocess.py must be modified to work with other MIDI files (the relevant "melody" MIDI part needs to be selected). The ability to handle this natively is a planned feature.
