Re: "exploding" a choirStaff

[Mats Bengtsson]

It's always very difficult to understand and find problems in
an uncomplete section of code. You have much better chances to
get relevant answers if you make a small but complete toy example
that illustrates what you tried and want to do (also, every so often,
you find the solution yourself during the preparation of the small
example). Also, always tell what LilyPond version you use, since
LilyPond keeps evolving from version to version.

Did you see the example called staff-halfway.ly in the "Regression Test"
document at www.lilypond.org? It shows the easiest way to create
additional staves in the middle of a piece. However, since LilyPond
always orders the staves vertically in the order they first appear in
the \score{...} section, this will probably not give the result you
want. The best solution is probably to use the RemoveEmptyStaffContext
feature and create all the staves already from the top of the score.
Something like:

\score{
  \context ChoirStaff <<
    \context Staff = separateSopranos{ s1*20}
    \context Staff = women <<
      \context Voice = sop {\sopm
                            \change Staff=separateSopranos \amensop}
      \context Voice = alt {\altm \amenalt}
    >>
  ...
  >>
\layout{\context {\RemoveEmptyStaffContext}}
}

The s1*20 should be modified to keep the top Staff context alive until
the voice moves up.
