David: I'm currently the maintainer of musixec.tex but I
don't know the history or where that code comes from.

Yes, that works; thanks. 

I just happened to discover the problem with \c{c}. Do I
need similar treatments for other \c{.} uses? There seem
to be other cedilla-ed glyphs in sfrm1000.pfb, such as
C-cedilla and t-cedilla.
