read up on midi everything your trying to do is very easy you just need to know some more about midi. Try to think of midi as a language that your mpc communicates with other hardware.
Main MPC "The one your sequencing on"
Second MPC "The 60 your playing drums from"
second mpc midi 1 out >>> main mpc midi in 1
This setup will allow you to play the drums sounds on the mpc60 second mpc , sending a midi note threw the cable to the main mpc. Which can also be recorded. The only thing missing is the return cable for the main mpc to the 60 , so when you reply the sequence it will tell the mpc 60 the second mpc to play what and when at what velocity and other parameters.
Take your midi cable and plug it from the midi out on the main mpc to the midi in 1 of the second one.
Now you gotta look in your mpc manual and learn how to change a track to send the signal on the correct midi channel and how to get your other mpc to listen on the correct channel. Also read up on how to change a track from audio to midi.
