Chapter 15: Editing Basics 219
Deleting a Playlist
You can delete a playlist from a session entirely.
However, since playlists take almost no disk
space, you don’t need to delete them for space
reasons.
To delete one or more playlists from a track:
1 Click the track’s Playlist Selector and choose
Delete Unused from the pop-up menu.
2 Select the unassigned playlists you want to de-
lete. Shift-click to select multiple playlists.
3 Click OK to delete the playlists. This operation
cannot be undone.
Multiple Undo
Pro Tools 6.1 can keep track of up to 32 of the
last undoable operations, allowing you to return
to a previous editing state. Pro Tools 6.0 and
lower support up to 16 Levels of Undo.
The Undo operations in Pro Tools are stored in a
queue, in the order in which they were invoked.
When choosing Edit > Undo, the most recent
operation is undone. If you choose Undo again,
the next operation in the queue is undone. You
can also choose Edit > Redo to redo an opera-
tion, which moves back through the Undo
queue by one step.
When the number of operations in the Undo
queue reaches the maximum Level of Undo,
performing another undoable operation will re-
move the oldest operation at the bottom of the
queue.
For example, suppose the following operations
have been performed, with item 1 being the
most recent (first in the queue):
1 Region cut from track
2 Region pasted to track
3 Region slid forward
4 Regions shuffled
5 MIDI note trimmed
6 MIDI note inserted with Pencil
In this example, to Undo the region shuffle, you
would have to choose Edit > Undo four times,
which would also Undo the first three opera-
tions in the queue.
If you then choose Edit > Redo, followed by an-
other edit operation, such as a region trim, the
Undo queue would then be:
1 Region trimmed
2 Regions shuffled
3 MIDI note trimmed
4 MIDI note inserted with Pencil
To undo the last operation:
■ Choose Edit > Undo.
– or –
■ Press Control+Z (Windows) or Command+Z
(Macintosh).
To redo the last undone operation:
■ Choose Edit > Redo.
– or –
■ Press Shift+Control+Z (Windows) or
Shift+Command+Z (Macintosh).
When deleting a track from a session, you
have the option of deleting or keeping its
playlists, so they can be used on other
tracks.
