There are 34 Pure Iranian Sets inside this package. In average, each set contains minimum 50 beats (approximately 34 x 50 = 1700 beats in total). The styles have their variations, fillings and a variety of intros & endings. You must remember that these styles are recorded by computerized Iranian percussion instruments, such as mixture of computerized Tonbak (also called Tombak, Donbak, Dombak), Daf, etc. Additionally the sets contain Iranian computerized (Roland D-50) sounds, such; Taar, Bandari Leads, Mandolin, Dulcimer, Banjo, Koto, Kanun, etc. So from now on, you can easily throw your both Sampler and D-50 away, since this set includes whatever an Iranian musician needs "Why Not All in One". Listen to the demo above, and judge yourself. The demo you are listening above is a short demo, in which different beats from these 40 sets have been presented.
