Website hosted with github pages that generates (not on the fly, it was pregenerated) game music using a LSTM neural network.
The data used was about 1 hour of midi files for classic video game music (think Final Fantasy 7 and F-Zero).
I used music21 in order to get data from the midi files and again to create midi files from the output.
The neural net was trained for about 8 hours (57/200 epochs wanted). I used a Intel i3-8100 @ 3.60GHz. I used Keras to build the model.
