I haven't used Akoustik in so long that I wasn't entirely confident of my choices for #1 and #2, but was clear that #3 was "live". The only real reason I thought #2 was Akoustik was the extra "noise" and "breathing". The reason I wasn't confident of my choice was that #1, which I guessed correctly to be Ivory, seemed to have compression artefacts in the lower register. After reading Shooshie's explanation, I now am unsure whether that was the Waves L4 Maximiser at work, or a reflection of the original samples.
Well, it doesn't really matter, due to the point of this exercise. All three sound passable (as the real thing), but clearly #3 for me was by far the most pleasing and relaxing to listen to, and gives me a benchmark against which I would measure my own efforts the next time I mic up an acoustic piano vs. using a VI.
The tweaking of #1 and #2 gives me more hope as well for sample-based piano VI's, but as everyope knows, I gave up on Akoustik long ago (and can't consider Ivory due to its CPU requirements) as I simply don't have that sort of time at my disposal and have quicker success with Pianoteq and General Music's DRAKE-based sampled/modeled pianos.
As recently as three to five years ago, it probably would have been pointless to even have this exercise -- that's how far "digital pianos" have come in that time.
