[Tex-music] pmx-tex: Why is there a bar after \changecontext

[Andre Van Ryckeghem]

Hi all,




In the musixdoc manual, section 15.4, page 76 is an extract in tex for
displaying the meters, i made a standalone version, i included here. In that
extract, displaying the meters,  there is no bar line after the meter.

used by pmx and so on.



Thanks for looking at it.

Andre

In trying to put a meter in in single staff, i had to remove a barline after using \changecontext, with in line tex. The result pdf is attached. I cannot see a difference between the two, i tried everything, as ie. adding files that are Although this item is not important, but i am very curious what i am overlooking. ==============
