I don't understand fully what is asked (because of my bad English), but i
have a primitive TeX command with no arguments, but that is te be repeated
for each note, because i have redefinitions of al notes (hu, hl, wh) that
are to be restored. I suppose the command could be changed not to be
repeated in a sequence of notes with the same length.
If this is a start of what must done, i could work further on it, perhaps
using '\pcil' from pmx?
Propably the lines are broken:
