I see no reason why Cubase does not work......admittedly it is a steep learning curve.....so I would suggest it is an installation or set up problem. Most Lexicon interfaces are windows compatible and Cubase sure is. I bet it is something simple....like a driver or input or output device not assigned properly. More info and perhaps we can narrow it down a bit and possibly provide a solution. Give as much info as you can like model number of Lexicon and the operating system of your laptop and explanation of what happened exactly when you tried to install and connect it.
