Need help saving from MPC 2KXL to zip disk then loading to l

HEy i just recently got this and havent got it down fully and im trying to save the song i made but everytime i save it to my 250mb zip disk as midi it comes out totally different sound. it doesnt have my sample or drums on it. its just a piano playing and i dont use the keyboard on any pads. i have all the sequences right and set up just need to save it as full song and into my ipod. help pleasee!

oh yeah and im using windows 7 if that helps and i have reason 5 if it helps also.

a MIDI file has no audio, you are hearing a piano because (I guess wmp) is playing back the sequence with the builtin tone generator (don't recall it's name).
If you want to hear your stuff on the iPod, you'll need to RECORD the audio from your MPC into your computer, possibily thru a soundcard.
MPC OUT - SOUNDCARD IN.
I don't know if you can record audio from external sources in reason since i never bothered with it, in case you can get a freeware audio editor like audacity and record the output of your MPC in audacity.
