Is there a default setting for bass wrap around?

[bcomp]

I sometimes just turn on my Pa4X and start playing without running a style or song. When I play a chord on the left side of the keyboard, the bass note will also play - problem for me is the bass notes seem to have a wrap around that stops the bass notes from going lower than the A2. I want all the bass notes to play all the way down to the C2.
Does anyone know if there is a default setting when just playing normally?
I am somewhat familiar with style warp around but when not running the style there seems to be no way to control the bass wrap around.

Thank You,
Bob
