I wish I could tell you. I have never worked with a sound module before, and if it just plugged and played with other programs, then I may be leading you down the wrong path. With synths, unless they are recognized by Cubase, you have to set them up if you want to have all the names and the banks and patches easily accessable. Maybe someone with more info on sound modules can post on this here.
Also, you might want to check out the download area of the unit's manufacturer. If it is a script that is needed, some companies have them made up for their products and offer the file for free on their websites.
Good luck on it, I know stuff like this is frustrating when it brings the wheels of creativity to a grinding halt.
