crossfader/drum rack mapping question

[bleep bloop bass]

I would like to be able to be dj'ing with a song playing on my "A" side and have my "B" side be a drum rack full of samples/cue points and I would like to have the crossfader jump from the a side to the b side as soon as I trigger any of the pads on the drum rack. any suggestions on how to do this? I can get it mapped to individual pads but I want it to cross fade over no matter what sample I decide to start on.

any suggestions much appreciated.

thanks!
