Robbo,
Did you know that, I didn't know you could copy yami styles and play them on a Wing, in pubic is that legal.... and will they sounds exactly like the T4 on the Wing.
It doesnt say Yamaha styles, its says Yamaha style format... which is nothing more then a bunch of midi information.
Totally legal, or yamaha would allready have sewed the hell out of Wersi. Its the same as all those soft-arrangers do. the copyright is not with the style format, but with the styles data itselves.
The main question is : what sounds better, a T2 style file played on T2, T4 or on Wersi?
