well..... not quite dead - more like it never got born yet. The population of working players who use arrangers is very small compared to the number of home users. My opinion is becasue they still haven't addressed the needs of the pro enough yet. Arranger keyboards are a pretty fair compromise to allow us to make a lot of music with a small unit, but in truth .... the real needs of the pro player are still a little off as far as most offerings in the market today. They all have "something", but none has "everything". I want "most", and I'm still searching for that "Camelot Keyboard"
