Chapter 19 Make global changes to a project 577
Open the Signature List
Do one of the following:
m Click the List Editors button , then click Signature.
m Shift-double-click in the Signature track.
The Signature List displays time and key signatures in a numerical list, and also displays global
score symbols such as repeat signs, double bar lines, and so on.
Create time signature changes
When you create a new project, by default it has one time signature that lasts for the entire
project.
When Show Advanced Tools is selected in the Advanced preferences pane, you can add time
signature changes to a project in the Signature List, Signature track, or Score Editor.
Create a time signature change
Do one of the following:
m Place the playhead at the target time position, then drag the numerals in the Signature section
of the LCD to set the new time signature.
m Click the Add Signature button in the Signature List, then edit the values in the Time
Signature dialog.
m In the Score Editor, drag the time signature symbol from the Part box to the target time position.
m Click the target time position in the Signature track with the Pencil tool, then edit the values in
the Time Signature dialog.
•
You can enter beat groups for compound time signatures in the Beat Grouping field. The
total number of beats in the bar is calculated by the sum in this field. For example, entering
the numbers 223, becomes “2+2+3.” The sum is displayed as the numerator unless the Print
Compound Signature checkbox is selected. Beat Grouping affects the way in which notes are
beamed together (in both cases).
•
You can also change the automatic beaming in normal time signatures. In 4/4-time “1+1+1+1”
produces four beamed groups (one for every beat), instead of the two groups displayed as
a default.
•
Select the Hide Signature checkbox to hide a time signature change in the score printout.
The signature is still displayed onscreen, but is crossed out, and won’t be included in the
calculation of spacing between notes and symbols. As a result, signatures may overlap notes
on the screen, but not in the printout. This can be used for notating cadenza-like passages,
which contain more notes than would normally fit the time signature.
