I took a little time to works with some of it this morning.
Well, basically, I took the Maestro Grand Piano, and, converted it into a soundfont(sf2) file. Then opened it in a Reason NN-XT Sampler. I added a Mastering Suite, and appropriate reverb. And, finally, created a Combinator in Reason to act as a wrapper for the patch.
I have to admit, it turned out to be a nice fat piano patch.
The down side is, that lots of folks couldn't even load it. The size of the soundfont is just under a gig.... But, you be the judge...
The sequence I used for this example is raw... So, don't interpret errors as a problem with the patch.
I've listed both mp3 and ape of the performance, in case you want to listen to both.

EDIT: I should also mention that this patch contains samples for "each" key/note in five(5) layers stereo. Thus, you can understand the reason for the size
