That's because you use the << \\ >> construct, which implicitly creates voices "1" and "2" in *both* staves. Please use explicitly instantiated voices instead and it should work fine. See the modified \score block below. I hope we would have less problem with this when issue #1316 http://code.google.com/p/lilypond/issues/detail?id=1316 will be fixed! Cheers, Xavier %%%% Modified \score block \score { \new PianoStaff \with { instrumentName = "Pf." } << \new Staff = "right" \with { midiInstrument = "acoustic grand" } { << \new Voice = "rightOne" { \voiceOne \rightOne } \new Voice = "rightTwo" { \voiceTwo \rightTwo } >> } \new Staff = "left" \with { midiInstrument = "acoustic grand" } { \clef bass << \new Voice = "leftOne" { \voiceOne \leftOne } \new Voice = "leftTwo" { \voiceTwo \leftTwo } >> } >> } %%%% End -- Xavier Scheuer <x.sche...@gmail.com> _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
