[chuck-users] what is this stk control change thing?

My confusion is deep and multifaceted, but just to get started, I gather it's a way of setting various instrument parameters, but how does it differ from like-named (where they exist) method calls? I made a Googley effort to find this explained, but failed. I would gladly accept an answer in the form of a link.
