Ivory is the best sampled piano I’ve heard. I could not wait for this to come out on windows. I have an old Kurzweil Keyboard and I just love the pianos on it, so when Ivory came out with sounds programmed and sampled by the same people I was excited to hear the result ....i was not disappointed. Because it was on Mac first I was a bit worried about the stability i needn't have been it was very smooth no problems, the samples loaded quite fast too. I’ve had no reason to use customer support so I gave a 5. As for features it’s just a piano but you can really tweak the sound to extremes and layer synth pad sounds so it dose more than you would expect. I had The Grand and listening to the examples of The Grand 2 and the Akoustik piano they still seem to have that same plunky sampled piano sound, Ivory sounds and responds like a real piano. I have played grand pianos in good sounding halls and rooms and Ivory has that rich and lively sound of the real thing sweet. Ok I like it a lot .
