And the manual for the Artist Control:

Personally, I hate to work without a control surface and I do feel that the benefits of hands-on control far outweigh mouse and keyboard control, especially in terms of automation. It just feels so much more musical and organic to move faders than to automate with a mouse. And yes, it helps me work MUCH faster, so no, it's not just about money.
For a single fader control surface, have a look at the Presonus Faderport.
Hope this helps.
