A previous OF NOTE post, “Controlling Staff Visibility of Tacet Bars in Finale”, illustrates how to hide unused empty staves in Finale:
A score where string sections are broken out into divisi on several staves for part of the score, but confined to their separate staves for other parts of the score would be an example of this.
