Global Score Settings
The Global Score project settings define global formatting options such as page margins,
spacing between notes, bars per line, and more.
Distance values can be displayed in inches or centimeters in the Global Score settings
pane.
To switch the distance value display between inches and centimeters
µ
Choose cm or inch from the pop-up menu at the top of the Global Score settings pane.
Settings that affect the general page layout (margins, for example) can be set
independently for the full score or just a part or it, indicated by the two input boxes. This
allows you to print out single voices with a page layout that differs from the full score.
(See
Creating Separate Layouts for Full Score and Parts .)
