I know that I have some key componants to getting to where I can do some recording, I just don't have a grasp on what else is needed for the puzzle. My end desire would be to record and burn to a CD . Here is what I have, 4 channel PA system that I can plug my downloaded instramentals into to accompany me as I play my guitar and do vocals. My laptop serves as the player for the downloads. There are Recording Out jacks on the PA head. Would this be the source of the intire sound to be recorded??? I have an interface gadget Behringer U-Control UCA202 that plgs into the USB on my laptop. How or if it is used I do not know. I take it that I may need to have some type of recording software but what is another thing I do not know.
