I need help

Hello friends,
I just got my MPC X I really need help with setting up.

I want to use MPC as sampler on my live perfomances. I am keyboard player.. I want to load samples in MPC and sync/controll the tempo through my Korg PA4x.
is it possible?
can someone help me please?

You can sync the MPC to the Korg PA4x... you just need to hook up a midi cable from MPC In to Korg Out. Then make sure that the PA4x is sending midi clock and that the MPC is receiving Midi clock. I am not sure how to do this for your specific setup, but it shouldn't be too hard. My biggest concern would be to see whether the PA4x or the MPC function better as the master clock.

For loading samples into the MPC and controlling it from the PA4x, this is definitely possible. You can load drum kits to control one shots per key on the PA4x, or load key groups that will allow you to play samples across the keys on your keyboard.
