pmx binary package in Ubuntu Trusty arm64

 PMX is a preprocessor for MusiXTeX that produces near-publication
 quality scores and parts with far less effort than would
 be required using MusiXTeX alone.
 .
 Among the new features are several that facilitate detailed editing,
 for example fine-tuning positions of dots, ornaments, and xtuplet
 numbers. It now also generates MIDI output!
