The Undo feature in the TD-25 allows you to undo any changes that you have made in a drum kit. Using undo resets all the parameters that have been changed back to their factory settings. This feature can be useful if you find you have made changes to a kit and decide that you're not satisfied with those changes.
Here's how to use Undo:
1. After you have made changes to a Kit, press press the function 1 (EXIT) button to return to the main menu (if necessary).
2. Press the function 2 (UNDO) button - "Undo all edits for this Kit" appears.
3. Press function 3 (OK). "Completed" appears briefly in the display.
(Note, Undo can be used only for the existing kit that you have edited. If you change kits, the changes cannot be undone using the Undo feature).
