PyMMPZ is a Python library and scripts for converting .mmpz files to midi. It's a pretty minimal set of functions as-is, and could possibly benefit from a redesign, with a more object-oriented API, so it can be used for more than just .mmpz to midi conversion. PyMMPZ is partially based on the MIDIUtil project by Mark Conway Wirt: http://code.google.com/p/midiutil/
