However, Yamaha removed the Japanese expansion pack from their download websites. There was a free 'Japanese' voice and expansion pack for PSR-S670/770/970 that came with 15 styles and 7 Japanese instrument voices that are quite usable, and is compatible to Genos. The free 'Vietnam' voice and style pack for PSR-S970 contains 12 styles and 18 Vietnamese instrument voices, also quite usable on Genos: The China expansion pack comes with about 33 different Chinese instrument voices, 2 China drum / percussion kits, and 20 Chinese styles. If you do not have a S970, you should contact Yamaha MusicSoft at phone number 1-86 to seek advice before you buy this pack.

Once the China expansion pack is installed with YEM 2.5.1, it can also be used with the Genos as well. The installation of the China expansion pack requires S970 instrument information file.

The 'China' voice and style expansion pack for PSR-S970 costs $99.99, and is compatible to Genos (you have to choose PSR-S970 as your keyboard in order to purchase it, it is not listed under Genos): I do not know of any free Chinese song styles and voices.
