Genos Voice distorting when playing two voices thru Cubase Pro 8.0.40.

Just got my Genos yesterday and since I use Cubase often I wanted to make sure they worked together well.
From the Home screen I have Active Bass Finger playing in the Left Part and CFX Concert Grand playing in Right 1 Part.
I didn’t want to have to stretch to play an octave down on the Bass (playing F0) so I went into Voice Settings and changed
the Octave from 0 to -1 so I could play it from F1 instead.
Without using Cubase it sounds fine…
However, if I go into Cubase and try to Record with those settings, the bass sounds distorted…
My first thought was that I had to turn Local Control off…
However, the Right 1 CFX Concert Grand sounded just fine…
So I went back and changed the Octave back to 0 and re-recorded playing the bass part an octave down (@F0) and there was no distortion.
Any other Cubase/Genos users out there?
Any thoughts?
