Glad I could help you out before. Unfortunately, I can't help you out very much on this one. I have not been happy with any sampled acoustic piano I've heard yet (and I'm not even a piano player!).
The Ultimate Piano by EastWest (www.soundsonline.com
) is not bad. I find most of them lack some bite to cut through. If you tweak up the filter or eq them, they lose their body I find.
So far, the only sampled acoustic piano I've heard that I really like is the Steinway B for Gigasampler. I like it much better than the Gigapiano.
