Andyjh,, sorry for the slow reply. I don't check this site very often. Mostly now and then to check on VEP & VIP updates. And to be honest,,, I don't know how the sounds are manipulated?? The guys that tune my pianos are known world wide for their work on refurbishing pianos, including creating and shapeing the soundboard to the clients desired sound, tone, etc. How thin it is and how that changes from the center of the soundboard to the outside edges!!! (Thicker outside, thinner inside,,, or numerous other possibilities). It is amazing how different the slightest change of the soundboard, materials, thickness etc., will drastically change the tone, and reaction to the vibrateing strings!!! But,,,,, as for Ivory, I'm sure your right. Theres no way they would sample all the variables possible?? I just know that the realism of the final product, (CD in a stereo), is to this point the best that I have found. I can finally create a nice round, open sound in the treble,,, while still haveing a strong robust bass, and have it tranlate to the same sound in a stereo! And yet, again,,, I must add that I have not had the oppurtunity to try Vienna's Imperial piano. Which I'm sure is a fantastic instrument. Someday,,,someday!
