I bought the ketron x1 oriental two weeks ago. the only thing I can say is that the arabic styles are very realistic as if you are hearing a real band playing and the arabic instruments are very real. I was a general music and roland user, I used to play on a gem wk-2 and on a e-500or but since I bought the ketron x1 I sold these two keyboards because they are like toys if we compare them to the ketron x1.
I just love this ketron x1, it is perfect.
