Cubase 6.5 Pitch bend also affects main volume

I’m having a problem when recording pitch bends on my M-audio Keyrig49, it also affects the main volume control at CC7.
So it turns the main volume up and down as I bend the pitch and records main volume data automation on cc7.
Can’t figure out how to disable the volume control.

Is there a master setting in cubase for default pitch & mod wheel controls?
