In addition to the ruler, time signatures affect the score display. All functions that rely on
the chosen time signature and bar positions (such as MIDI metronome click or Transform
window functions) are affected if bar positions are used to restrict a function to a certain
part of the project.
Key signatures
When you create a project, the key signature defaults to C major, unless you choose a
different key signature. The initial key signature affects the playback of Apple Loops in the
project. Key signature changes affect the display of MIDI notes in the Score Editor, but do
not have an effect on MIDI playback.
You can add any number of key signature changes to a project. When you add a key
signature change, it changes the key from the insertion point forward, until the next key
signature change is reached.
You can store up to nine signature sets, which are reflected in the Signature track,
Signature List, and Signature window.
Show the Signature track
In Logic Pro, do one of the following:
• Choose Track > Global Tracks > Show Global Tracks, or use the Show/Hide Global
Tracks key command (G).
• Click the Global Tracks button .
By default, the global Arrangement, Marker, Signature, and Tempo tracks are visible when
you show the global tracks in the Tracks area (or an editor). If the Signature track is not
visible, Control-click anywhere in the global tracks header area, then select Signature
in the dialog that appears. For more information, see Show and hide global tracks in
LogicPro.
Note: The Signature track must be visible—and must not be protected—in order to select
and copy signatures.
Open the Signature List
In Logic Pro, do one of the following:
• Click the List Editors button , then click Signature.
• 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.
