The docs are wrong - I'll change that! The FCCellFrameHold holds all the 
TGF frames with note entries, and the data structure also appears in 
empty measures with clef changes at the start.

Yes, that would delete the references to the TGF frames as well. 
Instead, change the clef to the previous clef.

FCCellFrameHold only handles start-of measure clef changes. 
FCNoteEntry.ClefIndex can get the clef value, but the actual mid-clef 
data is stored elsewhere. I'll investigate! Perhaps I can include it for 
the next beta update.

Correct, that's what CellFrameHold controls.

AFAIK, clef states can't be unlinked between score and parts.
