Changing from a single voice stave to a piano grand staff mid score
I am using v1.3 on windows xp.
I have to reproduce a score which has half of it written on a single stave.
Then it expands to the grand staff.
I have tried using the "hide empty staves", by creating with a full piano grand staff and only filling in the top stave. However, it does not hide the lower stave, even when I put a break at the point where the lower stave starts having notes.
Here is an extract to demonstrate what I mean :
I even tried hiding the lower measures via the measure properties, but the left hand brackets do not adjust accordingly.
Is this at all possible in v1.3 ?
