Along the last several comments,,, I could never warm up to the Korg overall sound or the OS.
I have owned several over the years... If I was to pick the model I thought was best it would be the PA2x...


I don't like the harmonizer or the effects set up....


I absolutely dislike the PSR line .. PSR2100 was the last I owned and it was a terrible instrument.

From what I heard on youtube ..the Genos sounds way better than what I have heard from PA4x let alone the PA10000.

Between the over valued Korg and the over priced Genos … the Ketron looks brighter

Thankfully I am totally content and don't need to keep searching like some of you
