Locally disable hiding of empty staves?

[Alexander Kobel]

Hi, all,


does anybody know whether/how it's possible to locally prevent staves
from hiding troughout a part of the piece? An example (and my best up to
now) is attached...

By the way, what happened to the LSR? Is there a mirror somewhere?


Cheers,
Alexander
