Hello.........Your problem is an exact mirror of my same problem last year when I bought my CS2x. You have done EVERYTHING correctly!!! What you probably didn't do is to install the necessary driver to make it all work. Nowhere in the manual does it even mention this!!!! Fear not.............

Go to the Yamaha link below and select the CS2x. On the CS2x page select CBX Driver and download what you need. You will find downloading and installation instructions on the download page. After I did this everything worked!! Good Luck


P.S. Have you downloaded a program called Tune'em Up?? It's a cool looking and functional computer program that lets you tweak all your CS2x sounds and controls from your computer.
