Why would ADDING to a style collection ruin anything...?

Thing is, other than legacy US styles, few arrangers have anything that could remotely be called 'contemporary' US material. Alternative, hiphop, emo, modern R&B, zydeco, all of these styles are as poorly represented as the styles from Mozambique, or Sierra Leone or any of the countries Ketron are franticly trying to cover. However, I'd be willing to bet that there are WAY more people in the US capable of affording an Audya, if only it addressed THEIR needs. But I'm not talking oldies and bigband... I'm talking the same kind of stuff you can find in a MotifXS, or M3, or FantomG.

You know... keyboards that actually DO sell in large numbers

I'd be willing to bet that the zouk styles will sound very contemporary (by zouk standards). Why not try doing that to US styles as well. You will be amazed at how many more you sell, if you style them for the majority of people that buy keyboards, not the minority (which is what arranger users right now are)...

Without even TRYING to break into the sounds and styles in modern WS's, you basically condemn any modern arranger to a dwindling niche market, and basic irrelevance and obscurity.
