I have it and it is a great sounding piano.

I have both of these free piano VSTis and they also sound very good. Plus my DLs of these did not contain any malware. Google/bing free piano vst and you will find a number of them.

One piano VSTi may not cut it for all of your songs. The three that I mentioned cover a lot of different piano tones and styles. I have a few more if you are interested, my music computer is not on right now.

Good luck and I hope this helps.
