"Lost Art" is a wrapper for a Python project called "MIDIUtil." (So, you'll need to install MIDIUtil through Pip for this to work.)
This is a script that helps writing MIDI files (which I consider to be a lost art-- I loved MIDI files when they were popular).
These classes use Python 3.x, and I don't think they're compatible with Python 2.7.
There are some example scripts in the root directory that use this.
game_maintheme.py is an original tune of mine. You can listen to it on this YouTube video.
kefka.py demonstrates the ability to change from a major key to a harmonic minor key easily. It can be heard here. Available keys are major, natural minor, harmonic minor, hexatonic blues, and heptatonic blues.
In a future version, I hope to be able to add swing tempos, but I might need to learn a little more music theory to get into the knitty-gritty of the math involved.
(Remember that MIDIs aren't like mp3s-- The files will likely sound different on your machine.)
