Protect Smart Tempo edits by locking a range in Logic Pro for Mac

When you’ve made edits in the Smart Tempo Editor using either hints or beat markers, and are satisfied with the results, you can lock the range containing those edits and continue working on the rest of the file. Locking a range protects that range from any changes made by additional edits, or by performing a new tempo analysis. When you lock a range, it appears darker in the main display and the overview of the Smart Tempo Editor, and additionally shows a lock icon to indicate that it is not editable.
