I do like the new pianos. At first bite, each has a good, clear attack and a realistic sound. The added pianos and features--the compressor, for example-- are also valuable. One concern that is not related to the program: I'm not sure that people who bought the original version of Piano V are aware of the initial discount. I received an email saying that the entire Arturia collection was on sale for a discounted price, but only after going to the site for the piano did I find that there was a discount for just the piano.
I do have a very few feature requests, but I'll put those in the thread dedicated to, well, feature requests.
