Connect Akai Mpc 2000xl to Korg Ms-20

hello, here what i have:
korg ms-20; mpc 2000xl; usb-midi cable "m-audio one"
how can i connect the korg to the mpc?
the korg works only with the computer.
please let me know.

Don't have this setup, but it sounds like you have the Korg MS-20 legacy controller (not the original MS-20 monosynth)...

The MS-20 that you have is a controller for the a software synth on your computer -- so you would have to hook your soundcard output into the MPC input to have the synth sounds get played into the MPC. I don't think there is anyway to use the MPC to control the MS-20 or vice versa.
