Need to save my song

So I made a beat that I really like from a Metroid song and I wanna get it off of the mpc. Usually I'll just record all the sequences as samples and use FLstudio to put them in order because I don't have much RAM to work with. But I'm pretty sure that I have nowhere near enough recording space. Is there another way I can do this? I have a MIDI cable, Audio cables, an Mbox 2 and Audacity. Any help is appreciated.

Just go into RECORD MODE and select RECORD>MAIN OUT. There you will be able to record your sequence like samples. Then export as wav files to FL. Simple like your boss.

...as long as he has enough RAM in his MPC to record into.
