Re: Two staves to one while dropping the bracket?

[Ralph Little]

Hi Mats,
I have a related question.
I have a score where I wish to use the \RemoveEmptyStaffContext on one
staff of a staff group only. The reason for this is that I have a part
which is separate but only exists for a few bars in the entire piece,
and I don't want it to occupy a line on every page of the score.
However, all other parts I do, even if they only have bars rest.

I can't remember exactly what I tried, but I think it involved using the
new \with syntax to add the HaraKiri engraver, like:

\score {
        \new StaffGroup {
                \new Staff \SoloCornet
                \new Staff \with { \consists "Hara_kiri_engraver"}
\TuttiCornet
        }
}
..or something like that.

I could put together a simple example if nothing comes immediately to
mind....

What happened is that lilypond just "hung".

Do you know if anybody has used this in this way?
Lilypond 2.2 BTW.

Regards,
Ralph

One solution is to use the \RemoveEmptyStaffContext and simply insert
multimeasure rests in the second stave. Then, LilyPond will
automatically remove the second stave and the opening brace on the
lines where there are no notes.

Example:

uppervoice=\new Staff \notes\relative c'{
c d e f g a b c c b a g f e d c
c d e f g a b c c b a g f e d c
c d e f g a b c c b a g f e d c
}

lowervoice=\new Staff \notes\relative c''{
c b a g f e d c c d e f g a b c \break
R1*4 \break
c4 b a g f e d c c d e f g a b c }

\score{
   \new GrandStaff <<
     \uppervoice
     \lowervoice
   >>
   \paper{
     \context {
       \RemoveEmptyStaffContext
     }
   }
}
