pad sensativity settings and other hidden screens?

I read a post on here about a month ago that told about several hidden screens for the 1k. one of them allowed you to adjust the sensativity for each individual pad. I tried to search for the post, but was unable to find it. Can anyone either hook me up to the post or go through the steps to get there. Also, any other hidden screens?

Hidden on pg. 89 of the manual, how could anyone find that?

Oops, I don't have my MPC yet. I was hoping it would come today. I know I did read about some hidden screens somewhere though...

the pad sensitivity settings where hidden in os 1.xx in later os there not hidden anymore.
