I do a LOT of Country. The Korg is very limited in its country styles. Doesn't even have a basic CW shuffle or Shoddish (2/4 country). I had to create my own. I liked a lot of the sounds and a lot of the styles, but not for Country. Ketron wins the CW war.
Also, the PA80's weakness in the intro/fill department and the lack of a decent harmonizer disqualified it for me.
