The ketron x1 is like the normal x1 (I think) and the oriental program is an addition that can be bought as an option. I bought my keyboard in lebanon, and I know the persons who contributed in the making of the oriental program and I must say that tese guys are incredible, they created the most perfect oriental percussions.

In the gem wk-2 and the e-500or we only have one oriental drum kit in each one, while in the ketron x1 we have 6 arabic drum kits. 3 drum sets and 3 others that can be used as a drum2 part. you can record an occidental drum part on drum1 and add to it arabic percussions on the drum2 part. like you can record a techno style and add to it arabic drums.
