PMX provides a preprocessor for MusiXTeX. pmxab builds a TeX input file based on a .pmx input file in a much simpler language, making most of the layout decisions by itself. It has most of MusiXTeX's functionality, but it also permits in-line TeX to give access to virtually all of MusiXTeX. For proof-listening, pmxab will make a MIDI file of your score. scor2prt is an auxiliary program that makes parts from a score.
