PMX does not know that clef changes change the position of the notes :-) Process your example without the C-command. You can then see that the 3rd beam ends below the note head so that PMX selects now \tbl instead of \tbu. A circumvention is easy. In the case of error, change "Ct c84 e a" into "Ct c84 e \let\tbl\tbu\ a". No further changes have to be made in this case, because the assignment of \tbu to \tbl is local within \Notes...\en because the series of same length notes within the current bar ends just after the change. Otherwise you should use something like: ... e \let\tblsav\tbl\let\tbl\tbu\ a \let\tbl\tblsav\ ... or more general: \\let\tblsav\tbu\ \\def\tbufortbl{\def\tbl##1{\let\tbl\tblsav\tbu{##1}}}\ ... ... ... e \tbufortbl\ a ... Hope this hilft -- Werner
