It seems that overriding #'remove-empty for Staff.VerticalAxisGroup has only an
effect if it is called prior to the first note of the staff. Any
\override VerticalAxisGroup #'remove-empty = ##t (or ##f)
after the first note does not have any effect.
Now, this is a problem, if the whole score consists of several different parts.
For example, I have a choral score with fugues and a soprano solo.
during the fugues, none of the staves should be removed (if e.g. the Alto sets
in 9 measures later, I still need the empty staff for them them), but during
the soprano solo, the alto, tenor and bass should be removed.
I tried using
\layout {
\context { \RemoveEmptyStaffEngraver }
\context { \Staff
\override VerticalAxisGroup #'remove-empty = ##f
}
}
and then in the music:
b1 |
% We want to remove empty staves only during the Solo!
\override VerticalAxisGroup #'remove-empty = ##t
R1*3 |
\override VerticalAxisGroup #'remove-empty = ##f
c1
Attached is a full sample file. I don't want the empty staves in measures 2 and
3 removed, but during the solo (measures 4-6) all empty staves should be
removed. Then, in measure 7, empty staves should no longer be removed...
Any idea how to implement this? Or how can I make #'remove-empty also work
after a staff has started?
Cheers,
Reinhold
