So I tried using the usb/midi for the first time on my ctk 2400. I get a error message saying device not recognized replace it. I'm using Windows 7 This keyboard is a week old I'm not going to return it because another one would probably do the same error message. The keyboard does not come with anything useful like a cd with drivers. Should I try wasting my money on another brand of cable? Its not just easy plug and play self install like a lot of people say. I feel like I'm missing the drivers or something. I know this is a simple kids learning keyboard so it should be easy to hookup, I should be able to use midi and expand its limitations. Please if anyone has any suggestions I would appreciate any help, I just want my new toy to work.
