Yes, this works great. I never realized what actually is the difference
between the combined Staff types, except the obvious visual appearance.

The difference is described here, but I failed to find it.

Thanks, and Merry Christmas!

Easier to just use

\new GrandStaff << ... >>

The only difference is the Keep_alive_together_engraver if I remember
correctly.

No, that’s not what the question was about. Helge is working on a harp 
part, and he wants systems that contain only MMRs reduced to one staff.

For that purpose it's not necessary to write this multi lines of rest 
measures in two staves. I would like to reduce the lines that have 
only rests to a single staff line. I.e. somthing similar like 
\RemoveEmptyStaves, but it should leave one staff line. I tried to 
adapt http://lsr.di.unimi.it/LSR/Item?id=307 and changed ChoirStaff

There’s one key difference between PianoStaff and ChoirStaff/StaffGroup: 
the Keep_alive_together_engraver. It has RemoveEmptyStaves work only on 
all or none of the staves in the PianoStaff. So you should do something 
like:


\new PianoStaff \with { \remove Keep_alive_together_engraver } <<
  \new Staff {}
  \new Staff \with { \RemoveAllEmptyStaves } {}
>>

That way only one of the staves gets removed.
(If you don’t use development versions or want it not to take effect on 
the first staff, get rid of the All.)

This is jotted down from memory, so please excuse eventual errors.

HTH, Simon
