hi!i've been looking for kontakt format Chinese instruments for a while, and i found a new site is called http://mystsonic.com/. they said it is still under construction on online manual video(no officially anounce yet). but the main hompage site is already done and exist since last month.

one of the product called Chinese Zither-GuZheng is very chracteristic as being a Chineese style plucking instrument. the sound are quite harp-like, go take a listen to their demo sound Chinese,and even newage,rock style.....
very attractive and interesting.
