navindra Thank you! I suppose the crucial question to answer (but may be impossible), would this performance have realistically been more pleasing with another VST?
I think perhaps it would not. I suspect that when coming to music to "listen", one brings a different set of expectations than when one comes to "perform". The former is free to just fall into all the physiological phenomena that make up the overall listening experience, while the latter, being focused on a perfect performance, is not free to experience, but is rather constrained by a very narrow set of goals and expectations, all of which are related to the sound. So, I suspect that all VSTs sound better to their listeners than they do to their players.
My personal experience suggests this is so. I almost always enjoy others' performances on a wide range of VSTs. Yet, my limited playing experience with those same VSTs leaves me focused on their deficiencies. I enjoyed your performance on the Ptq Steinway, and I enjoy Phil Best and others who play Ptq. But, when I play, I dislike the sound and focus on its deficiencies, making the experience less enjoyable.
I think it is entirely possible that the rest of us enjoyed your performance much more than you did for these reasons.
On related matters, I am unfamiliar with the sound of a CP80, so I am unqualified to answer that one.
However I do have Garritan CFX full version, which gets substantial praise elsewhere. I enjoy hearing others play it. i do not like its sound so much when I play it. To my ears, I am unable to enjoy the sound of my playing of Garritan as much as i enjoy the sound of me playing Pianoteq.
