Restore deleted steps in the Step Editor
Accidental deletions of one or more events, a change of mind, or an editing mistake are
inevitable parts of song creation. Fortunately, you can backtrack your edits easily in Logic Pro. You
also have the option of re-creating an event with the Pencil tool.
Undo the last edit or deletion
m Choose Edit > Undo (default key command: Command-Z) immediately after making the error.
Undo or redo multiple steps
1 Choose Edit > Undo History.
The Undo History window appears. The most recent edit (at the bottom of the list) is highlighted.
2 Click any entry to undo or redo all edits between the clicked and highlighted entries.
Important: A Redo list is not displayed until an Undo operation has been performed.
The Redo list appears below the Undo items. The first item that can be redone is indicated by
gray text.
Undo or redo an isolated edit operation
1 Command-click the edit operation you want to change.
A warning dialog appears.
2 Click Apply to undo or redo the edit operation. Click Cancel if you change your mind.
When the operation is applied, an isolated edit is undone or redone without influencing all edit
operations between the clicked and highlighted (most recent) entries.
Change step values in the Step Editor
Steps can be altered individually or as a group. When adjusted as a group, the absolute
differences between event values remain constant.
Alter individual step values
m Grab the step beam (with the Pointer or Pencil tool), then drag vertically.
The current value is shown in a help tag as you drag.
Alter several contiguous step values
m Drag across the steps with the Pointer tool. Vertical movements affect the value of each step.
The current value is shown in a help tag as you drag across each event.
Alter the values of multiple steps
1 Use any selection technique to select the steps you want to edit.
2 Grab one of the grouped (and highlighted) steps, then drag vertically.
The values of all steps are adjusted. If any of the beams in the group reaches the maximum or
minimum value, you can’t go any farther in that direction.
