Re: removeEmptyStaff one by one

[Mats Bengtsson]

The following lines will define a separate context type 
"RemoveEmptyStaff" that
can be used together with ordinary Staff contexts to do what you want:

\layout{
 % Define a separate context type corresponding to the
 % ordinary \RemoveEmptyStaffContext. The definition is
 % copied from ly/engraver-init.ly:
 \context{
   \Staff
   \name "RemoveEmptyStaff"
   \alias "Staff"
   \remove "Axis_group_engraver"
   \consists "Hara_kiri_engraver"
   \override Beam #'auto-knee-gap = #'()
   \override VerticalAxisGroup #'remove-empty = ##t
 }
 \context{
   \Score
   \accepts RemoveEmptyStaff
 }
}

Just use \new RemoveEmptyStaff for the staves you want to be removed
and \new Staff for the those that should stay.
