pyalsamidi provides a Python interface to ALSA's MIDI features. It really isn't polished, but it does work (on my computer at least).

The concept of a midi program is very general; Programs basically intercept midi events (the act of pressing a key or sliding a controller on a musical keyboard), and then respond in any way you can dream of. These scripts are just a few programs I came up with to demonstrate the pyalsamidi package.
