This seems really naff and will expose me as a complete idiot -but I have been trying to come to terms with my yamaha pr160- mainly to assist in song writing. well with time on my hands I read the manual and realised that with the odd press of the button, it displays the notes I am playing and also the notation -I've only had it a year! My playing has not improved at all but it has been incredibly helpful in not having to rely on others to do the notation for me.
