There are 6 Pure Iranian Sets inside this package. In average, each set contains minimum 50 beats (approximately 6 x 50 = 300 beats in total). The styles have their variations, fillings and a variety of intros & endings. You must remember that these styles are recorded by live Iranian percussion instruments, such as mixture of Tonbak (also called Tombak, Donbak, Dombak), Daf, etc. Additionally the sets contain Iranian (Roland D-50) sounds, such; Taar, Nai (also called Surnay), 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.
