Just buy it... I'm a professional pianist, mostly jazz, standards, Broadway etc and this piano is one of the absolute best VSTi you can buy at any price.. I've beta tested for a few companies, not Ravenscroft BTW, and own pretty much all of the top contenders and I keep going back to the Ravenscroft... I would describe it as a Yamaha with sophistication... It's bright and lively, but can be tamed, but it has an uncanny ring and clarity that no other VSTi piano I have tested has.. Notes are extremely consistent which is a big problem with some piano VSTi... It's not a woody, dark sounding piano like some Steinways. It's close to Ivory American D but with a lot more crispness in the sound but without sounding harsh.. BTW Delany's settings are out there on the net as are others and if you copy them the piano sounds exactly like his. One last thing is play-ability... You can catch notes with the pedal, no abrubt note off things happening and so forth.
Interface is really nice as well.
I've blathered enough.... Just buy it.. You'll love it especially at this price... Trust me...
