Intro to key signatures in Logic Pro for iPad

Key signatures are global events that affect all tracks in a project in Logic Pro for iPad. When you create a new project, the key signature defaults to C major unless you choose a different key signature. You can view, add, and edit key signatures in the Key Signature track and the display in the control bar.

The initial key signature affects the playback of Apple Loops in the project. MIDI, pattern, and Session Player regions in the project can transpose to match the key signature, depending on the Pitch Source parameter in the Region inspector. For information on setting the initial key signature, see Set the project key signature.

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.

If the Key Signature track is not visible, tap the Single Global Track pop-up menu, then choose Key Signature. For more information, see Show and hide global tracks.
