"Automatische Aufteilung von Noten"

[Bernhard Kleine]

I have the following code and want to add this snippet from the
Documentation:

\new Voice \with {
  \remove "Note_heads_engraver"
  \consists "Completion_heads_engraver"
  \remove "Rest_engraver"
  \consists "Completion_rest_engraver"

Adding it to \new Voice = "soprano" failed and adding to ChoirStaff
failed, too. Please help.

Thanks a lot!

Bernhard
