Chapter 4 Editing Regions 39
Undo/Redo
Did you make a mistake, such as not selecting all of the MIDI Regions, or perhaps you
moved them to the wrong place?
If so, this would be a good time to become acquainted with one of the most important
functions in Logic—the Undo. The Undo function allows you to undo the previous
editing step, should things go wrong.
To use the Undo function,
m Select Edit > Undo “edit function name”. If we were to undo the example above, the MIDI
Regions would be reset to their original positions, and you could re-attempt your edit.
Give it a try, even if you got the edit right!
To reverse the Undo:
m Select Edit > Redo.
To undo more than one editing action:
1 Select Edit > Undo History.
2 A listing of all previous editing actions will open. You can go “back in time” to any of
these edit operations. Click on one to see what happens.
3 To return to the most recent editing step, click on the most recent entry—namely, the
one at the bottom of the list. Cool huh?
Important: It is vital that you make the distinction between what can be undone and
what can’t. As an example of this—the Quantize or Transpose playback parameters do
not actually alter data. They simply change the way it is played back.
Realtime playback parameters such as these do not involve an edit operation (such as a
cut, copy or paste), and therefore the Undo function (and thus the Undo History) has
no effect on them. To undo a playback parameter, simply select the affected MIDI
Region, and adjust/reset the appropriate parameter to its former (or default) value.
