Hi Peter, From what you say about the locations of your equipment, I assume that you are connecting some kind of portable audio recorder to your keyboard and having made a recording, you then connect the recorder to your PC ?
There's a collection of Tutorials for Audacity here : http://audacity.sourceforge.net/help/tutorials which I think you will find useful.
