No offence.I suspect you will go back to Yamaha due to lack of styles/fill issues in Korg. That's what happened to most US/UK arranger players who play styles all the time. Not talking about SMF/ MP3 players.
Lack of style support/ style variety and poor conversions are the reasons.
Korg has along way to go( style support) in western market. They are better for Mid East/ euro/ Balkans like Ketron.
