Reply to Ipad sample controller for Traktor

Hey guys
I just got the Midipads software for my ipad and wondered if i could configure it to do the sampler section of traktor? i started kidding around but im stuck trying to get feedback of the samples like this guy:
I already own a DDJ-T1 and though of starting to use samples in my gigs, so this would be a cheap start for me.
i can make a 8x8 grid and 8 sliders, anyone know if theres a mapping for roughly that configuration? i dont have any trouble modifying it a bit to fit exactly my midi signals if that is what it takes.
Other app suggestions that i can control the sample section of traktor from would also be nice!
