My dealer got a couple of kn5000 keyboards in on trade the other day and I noticed a button I hadn't seen before - entertainer. Sits right above the Techni-chord button, where the kn6k has a solo button. Same thing, maybe?? He wasn't quite sure what it was for and I didn't have time to look it up, but I bet a few of you kn5k owners would know the answer. Would you share with those of us who have never owned a kn5k?
