I doubt if a big artist like Yanni would use VSTi's for solo instruments like flutes and violins. That flute is most likely a real player, that would be my guess. He does have an arsenal of quite talented musicians, and Pedro is a sensational woodwind player. It is most probably a real chinese flute.
Chinee Kong is great but has no sound like that.
If you guys know where is that sound coming from, please let me know.
OK I'm confused. ChineeKong have a great set of Dizis, so if none of their products sound like what you're hearing on Yanni's disc, maybe it's not a Dizi? I'm afraid I've never heard any Yanni, so I don't really know.
