mac-mpc3000 sample transfer???

hi,
couldn't find an answer yet, anybody help out ....?

i work on a apple g5 and saved all my sounds in .snd (mpc-format), but how can i get the soundz into my mpc3000 (without sampling it again)

a) via zip: has to be mpc formatted, so my mac doesn´t read/open it.
b)???

thanks
