Tempo Track: Extend Left — Logic Pro X keyboard command of the day

  Tempo Track: Extend Left

There is a whole world of work that can be done with a tempo track. The only thing I typically do with tempo is to create a tempo track for audio tracks that I have with no tempo information.

Move and copy tempo points in Logic Pro — Apple Support

Move the selected tempo point, replacing the previous one

In Logic Pro, Control-click a tempo point, then choose Extend Left from the shortcut menu.

The selected tempo point is moved left to the position of the previous one, which it replaces.
Note: This menu item is not available for the first tempo point.
