I used this program for a few months a while back. I don't really have great things to say about it. Firstly, you need to have a dongle with this software. The registration process is very overly complicated, and I had to spend hours figuring out how to get this thing to even run on my computer. After conversations with tech support, I finally got it going even though I had to use an annoying dongle. The installation also took a while - the samples are very big in this program. Usually that's a good thing if you have the space for it, you would think that the piano sounds of a higher quality. I have used a bunch of other piano softwares, and this one doesn't really stack up to the others. Maybe you can get it to sound natural if you are a MIDI wizard, but if you're just an average person with a home studio this program will probably scream Fake Piano. It seems to respond in a weird way to velocity changes coming from your midi keyboard where other programs don't. You are also fairly limited in the piano sound you get. A bunch of other competitors offer you options to change the sound of the piano a lot, but not so much here. I also wish you could change the distance of the "microphones", because that is very important to be able to control in a recording. This also adds to the piano sticking out like a sore thumb. I feel this is overpriced and disappointing. I would probably try a different one like Native Instruments Akoustik Piano, I had good results with that one. I would not buy it again, I sold it to a friend after using it for a while.
