Editing AD2 Kit Pieces?

Edit: For those interested in this topic, I repeated the question in the SONAR forum. Look there for a helpful discussion.

On the Addictive Drums 2 Edit tab, in the Kitpiece Controls section is a subsection labeled "Response." I can't figure out exactly what those controls do and how they interact with one another. The AD2 manual has one brief sentence, and the information I've found online so far hasn't helped much.
 
I've tried turning them up and down in various combinations, but don't hear a lot of difference. Can anyone tell me what you use the Response controls for?
