Ravenscroft 275 comes with its own sample player, the UVI Workstation 3 (requires v3.0.0 or later). Did you download the UVI Workstation? On the site, at the bottom of the Ravenscroft 275 page it notes: (I found several useful reference sites.) Check your manual and look for YouTube instructional videos. Turned out there were a number of fiddly steps involving both the keyboard and the computer that took me some time to figure out. I thought it was as simple as plug and play. But I know that at first I had trouble connecting my Roland with my Mac.

I can’t help you with Windows and I don’t know what keyboard you’re using. First, you need to make sure that your keyboard can communicate with your computer.
