Protect the position of events
There are situations when you will want to protect 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 will
move the events, resulting in out-of-sync footsteps. Logic Pro X has a feature that preserves the
absolute time position of events.
The protect and unprotect functions are available only when
selected in the Advanced preferences pane.
Protect the position of one or more selected events
m
Choose Functions > Lock SMPTE Position (or use the corresponding key command).
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
m
Choose Functions > Unlock SMPTE Position (or use the corresponding key command).
Change event values
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
Do one of the following:
m
Choose Functions > MIDI Transform, then choose a preset.
The MIDI Transform window opens, allowing you to transform the event. For more information,
see
MIDI Transform window overview
on page 467.
m
Add an event of the new type, then delete the original event.
Override the maximum or minimum value limitation
If a parameter of one of several selected events is altered, it affects the same parameter in all
events within the selection group. When you alter parameter values in a group of selected
events, the relative differences between parameter values remain unchanged.
Parameter values can only be altered until the (same) parameter value of one of the selected
events has reached its maximum or minimum value.
m
Option-drag the value.
This technique allows you to continue altering a parameter value in a multiple selection, even
when one of the selected events has reached its maximum or minimum value.
