HI there

I just got my new keyboard (like a musical keyboard, not the typing thing), and im very happy with it. I can record my sound with the line-in input on my computer and through the usb cable to use it as a midi keyboard. But now i was wondering could i plug the cable thats now in my line-in input in my mic-in input? So for example someone over skype could hear me play? :)
I've read somewhere that some mic-in inputs provide 5 volts of power for the microphone, and that that would be really bad for your keyboard! Is this true?
