Virus-Midiman Devices-Cubase mindtwister

[MotionChild]

Ok, it's probably been described 2030456 times on these forums but I don't get any wiser. I'm new to virus, midi and cubase and need help to set things up. I got a kc, most beatefull thing I've ever put my fingers on. But I don't have experience with hardware at all. Got also the midiman 2x2 usb/midi controller which confuses me. Also got the Delta 44 soundcard with Omni i/o controller. (the delta software controller confuses me to), and Cubase SX. Also I have a usb keyboard (radium 49) which I want to use as a master midi keyboard while I use kc to get programmed through cubase (midi patterns I mean). All midi in cubase has for some reason stopped working for me. It reacts but won't play a sound. If I use the midi key editor it does play sound. I've been struggeling for weeks trying to salve my probs but nothing works. That's why I turn to you and hopefully meet someone that can help. Know I need much help but it would be much appreciated. If you need more info to help me feel free to contact me on msn on motionchild@hotmail.com
Thanx in advance and to those who run these excellent forums.
