BFD 3.5 Scaling On Windows

Hello! As the title states, I cannot see the bottom of BFD 3.5 AT ALL! I want to pull the volume down on the hi-hat but no matter what I do to scale it down, it never works. I saw on the free BFD Player a scalable GUI. How can I scale it smaller

What resolution is your screen set at ?..
BFDv3.5 will scale by grabbing the edges with the cursor..
I have on a Tablet and it will scale from 1920 x 1080 down to 1455 x 913
