JOB 00 UNDO/REDO

1. Undo/Redo indication

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

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 editing, recording, or
job-related data change. (In the example above, the most
recent change was made by running the THIN OUT job
under SONG mode.)
• The UNDO job cancels the changes you made in your most
recent 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 recording sessions,
editing sessions, and jobs (with the exception of the SONG
NAME and PATTERN NAME jobs) carried out under
SONG, PATTERN, and PHRASE modes. It is also effec-
tive on PATTERN-mode patch operations.
• 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 often possible to execute an UNDO/
REDO job immediately – without moving into the cor-
responding job screens – by pressing s+j.
This feature is available, for example, from the SONG
PLAY screen.
