1. The R rests are misplaced (too high in the upper, too low in the lower staff).
2. If you comment out \key c\major (which does nothing), you get the following warning: warning: Change_iterator::process (): Staff = `up': /tmp/bee/piano.ly:6:21: warning: can't change `Staff' to `down': I'm one myself: \change Staff=dow n \voiceOne c1 \change Staff=up \oneVoice c R ..and the staff change is not done. The code: \version "2.1.34" \score { \context PianoStaff << \context Staff=up \notes \relative c' { \key c\major \change Staff=down \voiceOne c1 \change Staff=up \oneVoice c R } \context Staff=down \notes \relative c'' { \voiceTwo c1 \oneVoice R c } >> \paper{} } erik _______________________________________________ Bug-lilypond mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-lilypond
