What Nark is saying is to basically hook up your output on your MPC to the Record in on your MPC as well (Creating a sort of Loop).... Play your beat, and record it like a sample (Mode/rec), then save it.... Then take it off the Cf card and load it into you cpu and you will have a wave version of you beat on your CPU... You can use any program to convert it as needed....
I hope I explained it correctly, and I hope this helps.....
If that does not work, then download Audacity (Free) and hook up the output of the MPC to the line in on your CPU and use Audacity to record the beat. You will need one of these:
You will also need RCA to 1/4 adaptor
