I want to upgrade my rented Korg PA 600 to the latest OS. The Korg support site offers downloads for OS 1.20 or factory restore for 1.20. Since I haven't made any changes can I use the factory reset?

Tony and Don, I'm sure you both upgraded your 900's. What would be my best choice? My instinct tells me factory reset, but I wanted to check with you before doing anything foolish as I have read of problems with the upgrade. Praise the Lord/Graham lost complete use of his keyboard.

God Bless,
Don
