I think it was Donny who asked me this question but if it wasn't Donny I appologize and the right person will read this.
One of the most powerful features of the ketron products is to be able to customize the way the registrations can be set up to do the things you might like them to do rather than the way the factory might have liked them to do. There are dozens of parameters you can change by selecting on or off to suit your playing styles. On means that everytime you select a new registration, this parameter will change and off means that this parameter will not change when you select a new registration, even if the registration was programed with a different parameter setting.
On all Ketron models currently made you can make it so that when you change different registrations, the vocalizer settings will remain the same.
Go to Utility.....
Go to Registr.Mode or on XD9 Reg Menu
Go to Effects
Cursor down to Vocalizer and if it is "ON" change to "OFF".
Next press Save (F7)
Now, very important.......
Go to Save/Enter ....
Go to Power on Setup
Press Save....
Now, everytime you turn on the keyboard, if you do not want the vocalizer parameters to change when you are in registration mode, they will be the same on each registration.
