In pmx.tex, evidently \centerbar is used for centered pauses (with \pausc), while \CenterBar is used in multi-bar rests. I don't see any reason to change anything in pmx.tex unless it gets broken by modified definitions in musixtex.tex. At the moment it appears that changing \centerpause will not affect PMX but changing \centerbar may. So if Bob or someone proposes to change \centerbar, then please provide the proposed modified definition, so I can exercise PMX and see if anything gets broken.
