Canceling the Previous
Operation (Undo/Redo)
The function which lets a modified parameter value or
edited musical data to be restored to its previous state
is called Undo. The function which returns the para-
meter value or musical data from its "Undone" state
back to the edited state is called Redo.
The JX-305 lets you use undo/redo for the following
operations. This is convenient when you wish to can-
cel a change, or to compare your edits with the origi-
nal data.

Specified Part (Pattern Edit)" (p. 138)

5. Press [ENTER], and your changes will be
"redone," returning the value to its edited state.
* Undo/Redo operations must be done immediately after
you modify the data. Once you save the modified pattern,
the undo/redo operation will no longer be available. Also,
if you use a different operation to make a further change
to the data, it will no longer be possible to undo/redo to
the change that was made first.
When you execute an operation that modifies a large
amount of data, such as during pattern editing, the
Undo operation may not be available.
