Handling Signature Changes
Events on the Signature track can be selected, moved, deleted, and copied (drag them
while pressing Option or use the standard Copy and Paste commands). Multiple
selections are possible, even in conjunction with Regions, which is very useful when
complete parts of a song, containing signature changes, are to be copied. In this
situation, the Edit > Select Inside Locators option can be helpful. Note that the Signature
track must be visible and must not be protected, in order to select and copy signatures.
If you double-click a signature in this track, a dialog box opens, allowing you to edit the
signature.
Shift–double-clicking in the Signature track opens the Signature/Key Change List, where
time and key signatures are shown in a list style editor, along with other global Score
symbols such as repeat signs, double bar lines and so on.
Cutting 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 by cutting 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.
Transposition Track
The Transposition track shows global transposition events, which affect the
transposition of both Audio and MIDI Regions. In MIDI regions, it changes the actual
MIDI events themselves. Despite this data change to events, the Transposition track
works “non-destructively”, as the global transposition of MIDI Regions can be changed
multiple times, without actually altering any information. If the Transposition track is
set to zero, Regions (and the events they contain) are played back as originally
recorded.
