There is an example in the User Manual, section 1.1.3, Displaying Pitches, subsection Clef which shows a bug. The example is the one which shows the effect of changing the three properties, clefGlyph, clefPosition and middleCPosition. Changing middleCPosition does not cause a new clef to be printed, although subsequent notes are correctly shifted.
Here's an example which shows the bug in 2.10.20, and as the manual for 2.11.32 also shows the incorrect behaviour I guess it is still present in 2.11. { \clef "treble" c'4 \set Staff.middleCPosition = #4 c'4 \set Staff.middleCPosition = #0 c'4 } Trevor Daniels _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org http://lists.gnu.org/mailman/listinfo/bug-lilypond
