Can I edit preset programs?

You can edit preset programs included in all banks.

However, edited programs are only saved in your bank [U1] ~ [U5].
If you select factory bank [F1] ~ [F5] to save a preset program, it will be automatically saved to the same program number in the user bank.

For details, please see "Saving an edited program" in the Operating Instructions of this unit.
You can download the Operating Instructions from the Pioneer DJ support page.
