PMX is a preprocessor for MusiXTeX. It builds the TeX input file from a file in a much simpler language, making most of the layout decisions by itself. An auxiliary program makes single-player parts from a multi-player score. For proof-listening, PMX can make a MIDI file of your score.

The present version requires at least version 1.15 of MusiXTeX, running on an e-tex-enhanced TeX system.
