afraid your asking the wrong guy,I'm nearer 80 than 70 and was a pianist,having to change to a keyboard for the lighter touch.But quickly learnt that the built in rhythms in keyboards weren't for my era of music,also the manual isn't written for my age bracket either,so after nearly 2 years and almost ready to give it away,I by accident learnt how to get in to change the basics,and I mean basics...wouldn't part with it now.Wonderfull sounds and rhythms.Would have been a better instrument if the Panel memory buttons were accessable to the left hand
