Can anyone assist with the following:

I have a new Roland VR-760. When I try to select the Acoustic Bass sound (Ac Bass) it comes up but it is layered with an organ sound.

How can I unlayer it so I can hear just the bass sound (other than turn down the organ volume).

The manual just tells you haw to create a layer not how to un-layer the board so you ccan get a single sound.

And I see that the factory installed registrations are mostly layered.Is there any way to unlayer those other than somehow creating an unlayered voice and writing it to that registration.

Any help will be very much appreciated.
