It will scare the daylights out of the main arranger customer, (Home Hobby Player) so if you want something like that, you will always need to use it on a laptop and connect the laptop to the arranger.
While 99% of arranger customers are happy for new sounds & effects (Hence these types of VSTs are ideal to be added), in depth editing and creation are so for down the scale that you would need the Hubble space telescope to see them, thus there is no way arranger manufactures are going to lose sales just to please a few techie’s

90% of the arranger players will never use it...
Tough they will definately enjoy the fruits, because of what others create and share with this....
And no, you will not need to use a laptop for this, once arrangers get bigger touchscreens and acceptable processor power you could quite easilly create new drum tracks with this on your arranger...
I am quite convinced that espescially Yamaha will try and add something like this in. A nextvgen Tyros, as its actually easy to opperate withouth much knowledge of drum programming... If you would have played around with it then you would have seen how easy you can get good results with this. Just add one of the knobs (as seen on s970) to a parameter and there you go, easy opperable real time drumchanges...
Yamaha is king in hiding this technollogy behind an easier to opperate interface..
