i have an oxygen V1 so if thats what you got then do this:
1.load multisample program on a track in the sequence...
2.then left of program name is the word drum, change this to midi..
3. then to right side it says midi off, change this to 1A....
4.if your using an adaptor switch the switch to DC battery or if you are powering from USB from computer switch to USB power..
5.plug midi cable from keyboard midi out on oxygen and not the USB midi plug but the one that says keyboard...
6. the other end of midi cable goes to midi in 1 on back of MPC..
7. plug headphones in to MPC and you can hear the notes from the samples on MPC being played by you on the key board...
if you have a oxygen V2 then i dont know how to do that but im sure they are similar..
