Based upon your problem description, I would conclude there is a conflicting parameter 
set in the Ctrl Matrix. Check if there is a Parameter for VCF Cutoff - then check the Source 
and Depth values. The Depth value is probably set to a value that is offsetting to the VCF 
Cutoff value in the Scene.

Another idea - if your Voice is a Dual Layer, then the VCF Cutoff values for each Scene 
might differ substantially where you are not getting the anticipated results.
