yes that piano VST is showing promise. I have many piano VSTs including Alicia Keys which I really dont like at times and its a mammoth to load as well. Its sound lacks several harmonics that were not recorded properly I think.
Boz piano harmonics are decent without adding fake ones and the natural sustain is good too. It needs a bit of EQ to really get it to fit in general but thats true for many Piano VSTs. The tuning is a bit off on the lower notes but its definitely great for a rough version. I am waiting for the full version as well. I think its going in the right direction @bozmillar
