Note: When using Pickup Clock with audio regions, it is the region’s anchor (not the
region start point) that is moved to the playhead position.
Fixing Objects to Frames
In situations where you’re working with synchronized film, you often want specific sound
effects to play at a specific SMPTE time, rather than a particular bar position.
If the tempo of the piece needs to be altered at a later stage, the SMPTE time location of
events that have already been positioned will change. The Lock SMPTE Position function
prevents this from happening.
You can SMPTE-lock individual events in the Event List, or entire regions (along with all
events they contain). Objects locked to a SMPTE position display a small padlock symbol
in front of their name.
To lock an object to its current SMPTE position
1 Select the object.
2 Do one of the following:
• In the Event List, Hyper Editor, and Piano Roll Editor: Choose Functions > Lock SMPTE
Position.
• In the Arrange window: Choose Region > Lock SMPTE Position.
• Use the Lock SMPTE Position key command.
Note: Copies of locked objects do not preserve their locked status, whether copied or
pasted via the Clipboard, or by Option-dragging.
To unlock the SMPTE position of a locked object
1 Select the object.
2 Do one of the following:
• In the Event List, Hyper Editor, and Piano Roll Editor: Choose Functions > Unlock SMPTE
Position.
• In the Arrange window: Choose Region > Unlock SMPTE Position.
• Use the Unlock SMPTE Position key command.
All selected objects that were locked to their SMPTE position are now fixed to their current
bar position, just like normal events. This means they can be shifted by any future tempo
changes. The padlock symbol in front of the name disappears.
Positioning Bars to Frames
If you want a particular bar in the project to coincide with a specific SMPTE time, you
need to alter the tempo of the preceding passage.
