Have a look at pages 89-91 of the reference manual. This is an incredible upgrade over XS/XF, not only it is more flexible in terms of source-destination connections, it also has 18 response curves (XS/XF had only ONE: linear) and if that's not enough there are user-editable curves. (Not sure how many destinations can be tied to one source, as the manual doesn't seem to mention the number)
I can't even begin to imagine the result of parameters responding to motion sequences translated through those "irregular" curves. Kudos!
