I've never owned that particular model, but I did demo it next to a Tyros.

I found the Tyros to be head & shoulders above the Korg product in terms of user-friendliness. The sounds were all good, except I dislike the Korg piano sounds beyond words.

You should know I had bought the Korg Triton ProX about a year earlier and despised it. It was not the kb I thought it was...I could never get a good piano sound, so I dumped it rather quickly.

The Tyros' pianos are, IMO, far superior...
