Not being sarcastic Diki, but why would you WANT to mix two different styles? First of all, I'm not sure what you mean by 'two styles'. Do you mean like two (related?) styles in the same genre'?...or two totally different styles? And in the first case, wouldn't that just be a variation? I'm probably just not understanding what you're describing but since Korg opted to include it as a feature, it must have some validity. Could you elaborate a little on how this would work and in what instance you would use it. Do the two styles play simultaneously? Do the two tempo's automatically sync (assuming the two styles have different tempos). These probably sound like silly questions to those that understand the concept/process. If you've got a sonic example, please share it. That'll be the quickest way for me to 'get it'. Can't blame me though, the two instruments I still drool over (Rhodes & B3) haven't evolved much in the last (respectively) 60 to 80 years.

BTW, I've included both Nord and Kawai in my digital piano search but the models I like are both too damn expensive ($4500/3500). I just don't play that well .
