PMX does use \centerbar\pausc, and the new definition does break the centering. Redefining \pausc in musixtex.tex would not work unless pmx.tex were also modified. So if you do decide to go forward with redefining \centerbar, it would be less of a nuisance overall to leave pmxab.for alone and redefine \pausc and \PAusc in pmx.tex. Of course, even with that, there's a chance that there are other PMX constructions lurking that could be affected. --Don ------------------------------- [email protected] mailing list If you want to unsubscribe or look at the archives, go to http://tug.org/mailman/listinfo/tex-music
