Nice Jim, very professional. My only comment would be to raise the volume on the right hand. The balance between the vocals and the accompaniment is just right but (JMO) I think the volume on the right hand parts is a little low. BTW, if I ever did get another arranger keyboard, it would definitely be a KORG PA4x/5x. If I'm being honest, Korg is the only 'arranger' that had styles I actually liked. But that's just a matter of personal taste.
Take some time and learn all the 'hidden' goodies in the FP-e50. There's a lot of stuff buried in those menu's.
