Magic , an arabic kit is basically ana arabic DRUM kit which includes percussions samples (sounds) of middle easter percussion instrument. Thus enabling you to create (or in many cases the company creates) arabic (middle easter) styles so you can perform arabic music.

The best arabic kit I have heard so far is in the X1 which I currently own. Vega may compete but I doubt its at a higher sound quality. Next best thing would be PA80 as far as the arabic sounds (kits).
