Werner makes a good point here about the spacing. To elaborate a
little: My original solution would have given way too much space to the
double dotted quarter. In PMX the basic number of \elemskips allotted
to a note or rest is (32*t)^.5, where t is the duration (in whole
notes). So a double-dotted quarter should receive
(.25*1.75*32)^.5 = 3.74\elemskip .
The way I did it gave
(.25*32)^.5 + (.125*1.5*32)^.5 = 5.28\elemskip.
The way Werner did it (without the "X") gives
(.25*1.5*32)^.5 + (.0625*32)^.5 = 4.88\elemskip.
Now to correct this overshoot you would need to back up by
1.54\elemskip in my case, and 1.14\elemskip in Werner's. It is not
easy to get this exactly right using "X" , since that measures the
offset in units of notehead widths which are fixed, while the actual
length of \elemskip depends on how crowded the system is. While you
could try inline \off{-1.54\elemskip}\ , this would not be recorded by
PMX and could cause inaccuracies elsewhere in the line if PMX needed
to insert any hardspaces.
The best solution obviously is for the author of PMX to build
double-dotted notes into the the program :-)
