i thought that the Wersi/Tyros 2 Conversion demo was really quite good. It had captured the nuances of the instruments just like the T2 but the sound quality was not as high but i suspect thats more to do with the way it was recorded. If Wersi can pull this off with all makes of keyboards then they have moved up to a whole new level in terms of an "open system" . Can anyone tell me if they had to tweak the style after the conversion ?

Well done Wersi.
