I'm confused by what you mean, control the MPC with the Kaoss or vice versa? If so, Both of those are a no, or a "not worth the effort". The Kaoss looper is weird in that each loop is individually triggered like a note, which is why it doesn't play well with others. At this point mine has been relegated to "scratch pad" for my "Groove" area, I'll use it to figure out where I want the energy on my drums, then redo the drums with my drum-machines, and slowly fade it out.
