To delete all orphan aliases
µ
Choose MIDI > Alias > Delete All Orphan Aliases (or use the corresponding key command).
Converting an Alias into a Real Region
You can use MIDI > Alias > Convert to a Region Copy (or the Convert Alias to a Region
Copy key command) to make a real region from an alias; its contents are identical to those
of the original region referenced by the alias, but its playback parameters are those of
the alias. As a real region, you can freely edit it (or the original parent region, without
affecting the new real region).
Note: You can also double-click an alias to open a dialog that asks whether you want to
create and edit a real copy, or edit the original.
Creating Region Clones
You can create another version of an audio region in the Arrange area—a cloned
region—which is comparable to a MIDI region alias.
To create a cloned region
µ
Hold Option-Shift while dragging an audio region.
Whenever you adjust the start or end point of any of these cloned regions, all other cloned
regions are adjusted in the same way.
To make several cloned regions independent of each other
µ
Select the (cloned) regions and choose Audio > Convert Regions to New Regions (or use
the corresponding key command, default assignment: Option-Command-R) in the Arrange
area.
Cloned regions that are made independent in this way can have their start or end point
altered without affecting all other cloned regions.
To convert several selected regions into audio files
1 Choose Audio > Convert Regions to New Audio Files (or use the corresponding key
command, default assignment: Option-Command-F).
