Actually, I believe that the average buyer has all they want from these arrangers. They have fast, easy music creation...withot or without lots of
(or ANY) musical training.
I keep reminding myself that as a pro, I am in the minute mirority of arranger users that perfrom on stage, worldwide. I'm sure most of these units sit home.

Bottom line - As long as they make something that enables me to entertain a crowd....I'm open to suggestions !
