This is a simple test where I tried for the first time to create a music animation from a midi source file. The goal of this small project was just to get it working and not to create a reusable implementation.
To archieve this I did the following:
1) Downloaded a midi file from here: http://www.midiworld.com/
2) Created a mp3 file based on it here: https://www.conversion-tool.com/midi
3) Created a json file based in it here: https://tonejs.github.io/MidiConvert/
4) Loaded everything into Blender (except the .mid file, it is not actually needed anymore)
5) Run the longer script to prepare the data from the json file. (For every object it creates a long list that contains a zero or one for every frame)
6) Use that list in Animation Nodes to control the animation.
