MIDI Advice

Need a bit of advice regarding my setup and MIDI. I have my MPC 2500 sync'd to Cubase SX via an Edirol UA-25 interface. What i was looking to do next was add my microKORG to that. However although i can hook the synth up to my computer via audio through my Mackie 1402 VLZ desk im not sure on how i would still use the MIDI from the synth on my sequencer as the Midi input and output is being used by my MPC. Is there a way to pass the synth through the MPC to my computer to control and write midi data from the microKORG?
Any advice and suggestions are welcome,
Thanks in advance people.
