I gave in to trying ivory,the self-proclaimed greatest virtual piano ever made,and i am very impressed.It has 10 dvds and you need 2G ram they recommend.Being mainly a piano player i thought i would get a good piano,which it is. The only thing i wonder,on a real piano ,when you slowly press down say a bass key so the hammer moves too slowly to strike a string and hold them down,then strike a higher note or notes,the lower bass notes that are being held down will sound,they will resonate clearly till released.This doesn't happen in ivory at all,in fact you cannot even slowly press on a key without a note sounding.Maybe this sounds a little petty but when i hear a claim such as from these software companies,all of them,the thing should really mimic the instrument in all aspects.Especially since it costs so much.So i have to question the way these geniuses really do record these instruments,note for note with such perfection,as they claim.Nothin like the real thing folks,but who can afford that?
