Eldartford, I'm not sure whether you've heard (of) the Rachmaninoff recordings by Telarc called "A Window in Time" but they involve the use of a Bosendorfer reproducing piano. The producers were able to transcribe the rolls to digital form eliminating the mechanical aspects associated with piano rolls. As I mentioned above, it really is quite difficult to tell these were performances from rolls and mechanical playback. I'd bet if I played them without telling someone, most wouldn't be able to tell they were not recordings of a live performance. If you haven't heard them, and you're at all interested in the technology, give them a listen. Personally, I prefer the 1st volume of his own works.
