Editing Signatures
You can edit existing signatures in the Score Editor and Signature track by double-
clicking on them. The Time or Key Signature window appears, allowing you to make
the desired changes. Moves are achieved by selecting, and dragging, signatures.
Editing Time Signatures by Cutting and Merging Bars
You can use the Scissors tool in the Signature track to cut bars. As an example; to divide
one 5/4 measure into a 3/4 and a 2/4 measure, cut it at the fourth beat of the 5/4 bar.
If you make a cut in the middle of a bar—in a section where the time signature doesn’t
change—two corresponding shorter measures will be inserted, with the original time
signature resuming after the cut.
Likewise, it is also possible to merge two subsequent measures into one longer
measure, by using the Glue tool in the Signature track.
Deleting Signatures
You can delete all signatures in a project, except the initial time and key signature.
To delete a signature, do one of the following:
m Select the signature in the Score Editor, Signature List, or Signature track, then choose
Edit > Delete (or press Backspace).
∏
Tip: To erase all time signature events, choose Edit > Select Similar Objects after
selecting a signature, then press Backspace.
m Click the signature with the Eraser tool in the Score Editor, Signature List, or Signature
track.
Creating and Choosing Signature Alternatives
Signature alternatives are just that: alternative versions of all signatures on the
signature track.
To create an alternative signature track:
1 Choose a number from the Alternative pop-up menu on the Signature track.
