my mpc 2500 will not load anysound.....

when ever i load my sounds into the memory card using a card reader the it goes through everything is fine until i put the flash card in the mpc it loads like normal
but theres no sound. why am i doing sumthing wrong because when i put in a card i bought from sample kings it works fine

Are your samples in 16 bit, 44.1khz format??

how would i know or how could i find out

i just want my mpc to play my drums on the flash card that i loaded when ever i put the flash card into the mpc
i see kits that i loaded but i can't hear them when i push do it.
i think im doing something wrong

you can find out in your computer
if your samples are not 16 bits 44khz they wont load on the 2500
