\RemoveEmptyStaves does not work primarily because \PianoStaff has the Keep_alive_together_engraver. You should remove that one (or not use \PianoStaff) and then invoke only the second Staff as \new Staff \with { \RemoveEmptyStaves } { ... } If you don't want to retain the upper Staff with rests only when the lower Staff has notes, things are a bit more tricky. Basically, you'll arrange to have your whole PianoStaff removed on demand, give it a remove-layer of #0 but put _another_ copy of the first Staff (better though a rest-only variant of it) in parallel with the PianoStaff, giving it a remove-layer of #1. That way it will only survive into the final score when both staves in the PianoStaff will die. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
