Bill.., this is a problem we've been talking about for some time with arrangers. Their styles although written very well.., are starting to fall behind the times. There's a generation change happening here, and the arranger makers aren't keeping up with that. Even the styles they consider to be "modern versions" are still behind.
The problem I see (or should I say hear) is that these keyboard companies have the wrong types of musicians creating the modern styles. It would appear that this team who does a very good job at creating the more traditional styles are also the same team trying to replicate the more modern styles as well. When that happens you end up with modern styles that aren't quite there.., or Hip Hop styles on a current arranger that sound more like Cheese Hop.
