Hi Mike
Yamaha music education is massive in a lot of Asian countries (They teach from very young) on all sorts of Yamaha instruments including keyboards and Electones. (Yes they are still made, and like the keyboards they sell them by the truck load)

Another point to note is that in all the keyboard music completions around the world, most are dominated by Asian players.

Type Yamaha Music followed by the country (Not all countries are represented) into Google to see what�s out there. (This includes the Yamaha keyboards which replace a lot of the Western styles with Asian styles)

You think Yamaha is big in music, but you don�t realise just how big until you look all around the world. (Roland and Korg are just cottage industries in comparison)

Hope this helps in your quest.

Bill
