Hi Danna.

There is a big difference in quality between the mic and line inputs on most computers. I wouldn't recommend using the mic input for anything, but the line input should produce acceptable quality with a digital piano. If you only have one input socket on your computer, you will have to select Mic or Line through the windows software mixer.

Lots of our students are using standard line inputs with excellent results.

Mike is right in that the hardware he suggests is far better quality, but it is more expensive.
