Unlocking the timeline and editor playheads
By default, the playheads in both the timeline and the editor stay centered in the middle of the GarageBand window once they reach the center. When you are working on your project, you may sometimes want to see a different part of the project in the editor than the one shown in the timeline. You can “unlock” the two playheads, so that the timeline and editor can show different parts of the project.
When you unlock the playheads, they continue to move from left to right, rather than remaining centered. When they reach the edge of the visible part of the window, they continue to move. You can scroll either the timeline or the editor to see a different part of the project as you work.
To unlock the timeline and editor playheads:
Click the lock icon (with the two triangles pointing down) in the lower-right corner of the timeline between the scroll bars.
Click the lock again to lock the playheads, so they remain centered in the timeline and the editor.
