When you look at high end drum VST's and ask yourself why they sound so much better then arranger drums, the answer is in the dynamics..
Here is a video of my favourite drummer in Logic X..
If you watch the whole video, you should have a great idea how with two or three knobs, you could change the whole drums in a style quite dynamically..
If you make the styles follow the drums, you could really build dynamic styles that change and follow your playing... So who is going to take this technollogy and build it into the future arranger.. The tech is there..

This is a great video Bachus. So far Korg pa4x has great drums. I do think Yamaha has all this, but they just don't want to implement it in their arrangers. And I also think that Yamaha drums are really bad when you compare let's say price of T5 to what kind of drums you get. They don't even offer expansions. Too bad, because the rest of the sounds are really good. They do lack some character . Thing is not enough people demand it, and they can get way with it.
