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..
