I started the other thread....great minds think alike!
The topic started for me when someone mentioned PianoTeq (a modeled piano)
Up until that point I only had sampled piano plugins. And had thought sampled instruments were superior.
But after doing some Googling, I found out that this is not always the case.
I still prefer Superior Drummer 3 (sampled drums @ 320GB) to any modeled drum software, but PianoTeq seems to be better than most of the sampled pianos I have.
