… on Arrange Level
When you click on the UDL button, or double-click the background area above or
below the list entries (if visible), you move up one level in the Folder/Region hierarchy.
This allows you to see all Regions in the current song (or folder). On the Arrange level,
the list has the following columns:
Position
The start of the Region.
Name
Name of the Region. Double-clicking on the Folder name switches you to the display of
its contents. Double-clicking on an audio Region opens the Region in the Sample
Editor. A click on a MIDI Region returns you to event-level editing.
You can edit the name with the Text tool.
Track
Displays the track number. You cannot edit this value here (you could totally destroy
your arrangement if you did). If you want to move Regions to other tracks, do it
graphically in the Arrange window.
Length
The length of the Region.
