My idea of the ideal style setup is to have a total RAM based system. You buy the arranger KB with NO on board styles. Maybe it comes with a couple of hundred styles and you load it up with 200 styles of your choice! This way if you want to have 20 8beat and 20 16beat etc., you got it! You create your own arranger style based KB.

Dream, Dream, Dream, Dream, Dre-e-e-e-m!
