Hi Pose!, This is interesting. I'm a guitar player that uses backing tracks made on my psr2100. Do you mean that you make midi backing tracks on the keyboard and play the guitar thru the keyboard? I know how to record the tracks in the keyboard...but how do you record the real guitar? Does it save as midi? I haven't tried this so i'm not sure how to do this but it does sound like a time saver. Usually i'll record all tracks using the onboard 16 track recorder and not using live guitar. If you could give me the dummies version i'd appreciate it...lol
Take Care, Larry
