After 1 1/2 years on my KN7 I found Favorites. I am now using Favorites for all the midi files and technics files that I will sing or play with. If I am not mistaken there's room for 360 songs. I am even putting Keyboard settings in them.

I am giving in a little -- playing with a midi files still feels like playing with a tape recorder. I did that many years ago as a guitar player. Progress??? I guess I'm getting old.
Have a good one, John C.
