Someone asked a few days ago why you need that many sounds. Now my question is why do one need so many styles. Be creative just use the onboard tools of your arranger to make the styles to your liking. No need to buy expensive software if you already own an arranger. Just be creative just like in the old days when arrangers only had about 100 styles. Just my opinion ofcourse.
Most modern users (Particularly younger types) require everything to be done for them, (Just press one button) and the fact that they would need to put some effort in, is completely alien to them, thus it gets discarded.
