Re: rearrange staff grouping
Reply #2 –
I think Paul may be asking how to add the additional staves and how to group them.
<Atrl+A> will add a staff.
<Alt+Enter> on the active staff will get you to the staff properties where you can set the type in the "Visual" tab. Select type depending on what you desire with respect to grouping indications and whether barlines extend to surrounding staves.
Staff properties will also allow you to set MIDI channel and instrument choice - amongst other parameters.
