Hi,Scottyee.
I do not plan to buy GW-7 for my son. IMO, GW-7 is hard to operate, especially that it does NOT have registration-memory feature like Yamaha PSR series. I think it is more approriate as a second keyboard for those interested.
As described in the manual, GW-7 has about 20 built-in chinese styles. I chatted with an employee of Roland China today, he assures me that GW-7 will be marketed to US although the built-in voices and styles might be slightly different from those in China.
You do not need to tune the keyboard to play Chinese music. The PSR 2000 sold in China is not different from that in the world. Shiyu just uses the built-in voices and styles to mimic the voices and styles of Chinese instruments.
Afterall, there are only a few people in China actually own PSR 2000, so there is almost none DIY autocompanion styles. I am also searching for Chinese Styles. Once I find one, I will definately email it to you.
