Undo/Redo - Roland MC-909 Owner's Manual

Undo/Redo

Here's how you can cancel the results of editing or recording a
pattern or song.
1. Press [MENU].
2. Use [CURSOR (up/down)] to select "Undo/Redo."
The object of the Undo command will be displayed. For
example if you are undoing a Microscope operation, the display
will indicate "Undo Microscope."
3. To execute, press [F6 (Execute)].
* To cancel, press [F6 (Cancel)].
Undo can be executed for a pattern (pattern editing,
microscope, and recording) or a song (song editing and song
recording). Undo cannot be used for sample editing or patch
editing.
After executing Undo, you can use Redo to revert to the
previous state. After executing Undo, you can execute Redo by
performing the above procedure once again.
