Mid east /east Euros use Korgs/used to be Roland, and Solton(ketrons) in general.Why?
sample loading and user styles written by local dealers/sharing.

Yamaha however rules in Anglo and asian world(where more pop , western covers than ethnic music is played).I'm talikng about Malaysia, Indonesia,Japan, Fillipines etc (not China(newly)India where they use more ethnic sounds/styles like mid east). Mostly where 4/4 straight pop or rock oldie standards.Add that to biggest 3 rd party styles on the planet.
