PMX builds a TeX input file for MusiXTeX, based on a PMX input file in a much simpler language, and making most of the layout decisions by itself. All data are entered into a single file for the full score, up to 12 parts. An auxiliary program makes parts from a score. PMX has most of MusiXTeX's functionality, but it also permits in-line TeX to give access to virtually all of MusiXTeX. For proof-listening, PMX can make a MIDI file of your score.
