John, it does NOT have a start-up Registration. You have to make your own. Just create a new Registration, save everything you want to load when you power on, name it "John's Start-up" or whatever you want. When you turn the keyboard, select this Registration.
You will have to take note of what Parameters you have to checked to save in the Registration.
Be sure to SAVE the Registration, then SAVE the Bank! Yamaha does not make it simple.
