Elizabeth, if you need help with becoming proficient in recording and burning your CDs may I suggest you go to Bill Norrie's site which covers just about everything you need to know about anything to do with keyboards, particularly the KN7. I have learned so much from Bill, he has an easy relaxed way of explaining things.
I don't know exactly what the website address is but try contacting Bill on
"Bill NORRIE"
if that doesn't work, try contacting him through this Forum.
Good luck!
