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.
Change event values in Logic Pro
You can change the event values shown in the Event List Value, Number, and Channel
columns by using the mouse as a slider or with text input. You can not directly alter the
event type in the Status column.
You can also rename regions or folders, but not events.
Alter the event type
In Logic Pro, do one of the following:
Choose Functions > MIDI Transform, then choose a preset.
The MIDI Transform window opens, allowing you to transform the event. For more
information, see Logic Pro MIDI Transform window overview.
Add an event of the new type, then delete the original event.
