People you are wrongfully blaming EMC ..This is great software..
The reason the "bad" sounding styles come about...the method of the sounds from the original manufacturer's sounds..For example, with the Ketron X1, the styles conversions that used the strum guitars never did sound right..the fault was the design of the strums..EMC remaps and re-formats the style..it does not edit the sounds...If a converted sound doesn't work..edit the style, or move on...there are a zillion styles to choose from..
Personally I think EMC styleworks is a major reason why top line Arranger keyboards have been so popular..
as I always say " a style is a style"..I would "Not" buy an arranger because I didn't or did like the on board styles..
Just my opinion in support of my old friend Klaus..
