Working with groups of tracks
Select a group of tracks by holding the Ctrl key while you click the track header of the desired tracks. Now you can adjust the
volume, panning, track color, and other track attributes simultaneously.
Using undo and redo
You have unlimited undo and redo capabilities in ACID Music Studio projects. Each edit you perform is added in the project to an
undo history, which allows you to quickly restore the project to any of its previous states. In addition, undoing an edit automatically
places it in the project’s redo history where it can be quickly re-performed. However, any new edit performed on the project
overwrites the redo history.
Note: The undo and redo histories are cleared when you close the project or exit the application.
Using undo
To undo an edit, click the Undo button ( ) on the toolbar or press Ctrl+Z. Edits are undone in the reverse order they were
performed.
Undoing a series of edits
Clicking the down arrow next to the Undo button ( ) displays the project’s undo history. The history displays as a drop-down
list with the most recent edit located at the top. Undoing an edit in the list requires all subsequent edits to be undone as well.
1. Click the arrow to the right of the Undo button ( ). The undo history appears.
2. Locate the edit to be undone. Notice that all subsequent edits are automatically selected and the total number of edits to be
undone is indicated at the bottom of the drop-down list.
3. Click the edit to be undone. The project is restored to the state it was in prior to the selected edit.
Undoing all edits

Redoing a series of edits
Clicking the down arrow next to the Redo button (
) displays the project’s redo history. The history displays as a drop-down list
with the most recently undone edit located at the top. Redoing an edit in the list requires all subsequently undone edits to be re-
performed as well.
1. Click the arrow to the right of the Redo button ( ). The redo history appears.
2. Locate the edit to be redone. Notice that all subsequently undone edits are automatically selected and the total number of
edits to be redone is indicated at the bottom of the drop-down list.
3. Click the edit to be redone. The project is restored to the state it was in prior to the selected undone edit.
Note: Clicking the desktop outside the drop-down list cancels the redo operation.
Clearing the undo history
You can clear the undo and redo histories without closing the project or exiting the application. After the histories are cleared, new
ones are created as you continue building the project.
1. From the Edit menu, choose Clear Undo History. A confirmation dialog appears, alerting you that this action permanently
deletes the current edit histories.
2. Click Ye s to clear the edit histories or No to retain the current edit histories.
