Reply to hardware compatibility issue and a question of realisticism

so, I have two questions/issues. one of them may have already been asked before, but I'm pretty sure the other one hasn't. so here we go.

1. I have a Numark 4trak, and the Midifighter Beatmasher Pro. my plan was to use the MF instead of the effects bar that came with the 4trak as it's probably more functional, and would just look cooler to use. however, certain buttons on the fighter trigger buttons on the 4trak. specifically loop presets. how can I get the Midifighter to only trigger things from the Midifighter?

2. I just want to know if this is possible (and if it is, how to do it). there was this thing in a video from a while ago of the Numark NS7 II

they used these 8 buttons as mpc-ish beat points for on-the-fly remixing of sorts. if possible, I'd like to be able to do this with the aforementioned Midifighter.

(I'm using the version of Traktor that came with the 4trak, also)
