play one pad with all keys??

Ok,Ok,Ok.you made me do it!!!!!!!!!!!!!!!!when i plug my keyboard into my z8 and load a sample,i can play the sample on all the keys right.straight away without changing keygroups or anything.i just wanted to know if i could just turn on the mpc,load a sample and play it with all the keys without changing keygroups ect.maybe (i am) im lazy but curiosity got to me and i was just wondering about it and after trying a few times,no joy.sooooo,being a curious fellow i posted and wish i had not.obviously i was not clear about the exact requirement.fook man.ive been in this game for years and it just seems too much trouble to work with people because they have a different idea.want to make something out of nuttin.
