2. UNDO/REDO target

• The two entries at the right of the screen identify the data-
change currently available for UNDOing or REDOing. This
will be the most recently executed patch, editing, record-
ing, or job-related data change. (In the example above, the
most recent change was a PATTERN-mode editing change.)
• The UNDO job cancels the changes you made in your most
recent patch session, recording session, editing session, or
job, restoring the data to its previous state. This allows you
to recover from accidental data loss.
• The REDO job, which becomes available only after you
execute an UNDO, cancels the UNDO and restores the
changes.
• The UNDO/REDO job is effective on PATTERN-mode
patch sessions, and on PATTERN-mode and SONG-mode
recording sessions, editing sessions, and jobs (with the ex-
ception of the SONG NAME and PHRASE NAME jobs).
• The UNDO job is effective only on the most recent data
changes. If you run a recording session and then an editing
session, for example, the UNDO will be available only for
the editing session. (But note that if you move to a record-
ing, editing, or job screen and then quit without making any
changes, this does not count as a session.)
• As soon as you execute an UNDO, the job name changes to
REDO. The REDO will remain available until you change
data again.
• You can undo and then redo the same change as many times
as you like (provided that you don’t make any other changes
in between). This can be useful when you want to compare
two versions of your data.
• Check the JOB 00 Undo/Redo execution screen to
make sure that the details are correct, and then press
e .
• As a shortcut, it is possible to execute an UNDO/REDO
job immediately — without moving into the correspond-
ing job screens — by pressing s+j. This
feature is available, for example, from the PATCH
screen.

1. Undo/Redo indication

• The screen displays the word Undo or Redo to indicate the
job that is currently available.
