Protect the position of events in Logic Pro
There are situations when you want to prevent certain events from being moved. For example, several note events may be used to trigger footstep samples that match an actor walking down a corridor in a movie soundtrack.
You have already created the music for this scene, but have been asked to increase the tempo to match several cuts of different camera angles in the corridor. A change in the project tempo moves the events, resulting in out-of-sync footsteps. Logic Pro has a feature that preserves the absolute time position of events.
The protect and unprotect functions are available only when Show Advanced Tools is selected in the Advanced preferences pane.
Protect the position of one or more selected events
In Logic Pro, do one of the following:
Choose Functions > Lock SMPTE Position (or use the corresponding key command).
Control-click the event, then choose Lock SMPTE Position from the shortcut menu.
Click in the Lock column for the selected events.
A small padlock icon appears in the Lock column of protected events.
This function ensures that events that fall at a particular absolute time position—1 hour, 3 minutes, 15 seconds, 12 frames, for example—remain at this position when tempo changes are made.
Unprotect the position of one or more events
In Logic Pro, do one of the following:
Choose Functions > Unlock SMPTE Position (or use the corresponding key command).
Control-click the event, then choose Unlock SMPTE Position from the shortcut menu.
Click the small padlock icon in the Lock column for the selected events.
Thanks for your feedback.
