[UNSOLVED] I can't get my Virus A to work with my Electribe

[mad synthisist]

I just bought the Virus and have read the manual but I can't get the korg to work with the Virus AT ALL. I have a midi to midi to USB cable, and I know they need to be on the same midi channel but I can't get it working and I've tried everything I can think of. The only sound I have got from the virus is the demo song... now my limited understanding is the sampler should be able to send sounds to the virus and then I can manipulate them. (am I wrong??) do I need a midi keyboard instead?? Please help me as I've wanted a virus for ages and now that I've got one, it's very frustrating not being able to use it!!!!!
