Consider the following score: \new PianoStaff << \new Staff = "up" { <> % this should do nothing... << \new Voice \relative { e''4 f e } \new Voice \autochange \relative { a'~ a g } \new Voice \autochange \relative { c'~ c b } >> } \new Staff = "down" { \clef F << \new Voice \relative { a d, e } >> } >>
Problem 1: why, on the third beat, is the alto voice (playing a g') displayed on the "down" Staff? Problem 2: delete the line saying "<>" and recompile. Now all hell breaks loose: the score acquires a third staff, which even eats the soprano on the third beat... (on the other hand, the chords on beats 1 and 2 are now nicer). Why? (I guess that the "up" Staff had a default, empty voice through the "<>" - is that correct? but it does not explain all). _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
