NI Razor Vocoder

I want to use a drum loop to excite a Razor vocoder. I’m using Cubase artist 6 and a PC. I can’t find a tutorial or anything online to help me. There’s a video for mac and logic (if you don’t know what I’m talking about, I want to learn how to do it but can’t seem to get it to work… I made the drum loop into an audio sample and used it as a vocoder that way, but it doesn’t seem to respond as well… I would really appreciate the help, thanks.
