Mpc Workflow need help.

Wayts up people!
Have question.

I am making beats using Roland, Motif for all my musical stuff, sometimes i can do drums on keyboards too, motif has some nice sounds, and its easy scroll thru different sounds.
For example i have Kick drum on track 1, so while my song is playing i just scroll thru different banks on Motif, so i can find sound i am looking for easelly!
I forgo† to say I am using MPC 2000XL as my sequencer, and i prefer do drums using my sample collection on MPC.
For example i load PGM 64 Drum sound (Kicks, Snares, Claps, Hihets), So i recorded my drums, i can put them on defferent tracks.
BUT HERE IS THE PROBLEM: I AM LIMITED - I CANNOT CHANGE SOUNDS WHILE I AM PLYING MY SONG ON MPC!
So i am trying to find the way to audition souns as i do on Motif.
I see i can load PGM with 64 kiks then record any of them and scroll thru all 64 Using SHFT+Program, drum1. So i can find kick that sounds the best with my music.
Than, if i want to scroll thru snares and i have PGM with 64 Snares, when i load them my kick drum is going to be replaced with one of the snares.

So my ouestion is: HOW CAN I SCROLL THRU DIFFEDRENT KICKS, SNARES, HIHETS ON MPC WHILE I AM PLAYING A BEAT, THE SAME WAY I DO IT ON MOTIF?
Or i need to buy couple more MPC for hihets and snares?
Thanks!

if those samples aren't loaded in RAM you can't play / preview them ...
at least on the 2000 it's like that

Thanks guys!

heres what i do...

I have a program made for all my sampled kicks, another one for all snares, and another for all hi-hats.

I will play my beat ( i already have the instrument samples layed out) then I load the kick program and put it in drum3 in the programs.

I find the kick I want, go to drum 2, a new program, and put it on the pad.

Then I purge my samples, load up the snares, and do the same thing, then same for my hi-hats untill I have a new program with all the drums I want.

This way, I can go threw fast and find what sounds I want becuz I can just audition them by pressing the pad.

Thanks eastcoast121 for your reply!
Seems its not so hard as i thought.

why not just sample the sounds from your module for each project. so you dont have to fuk around with midi for drums. then you can just sequence you instrument parts via midi.
