Firstly I would like to say that after listening to the Debussy demo of your new product, I had the first time ever experience of really not being able to distinguish what I heard from a real recording of a real pianist.
I really want to congratulate you for accomplishing this great task: To capture the steinway soul in such an unpreceding manner. I admire your skills as a sample developer! How great it is to just lean back and enjoy the music and not think for a second oh wait that didn't sound right..
If it is not a secret, I would like to ask you how the performer of the Debussy piece reacted to playing this new instrument. From the playing I must guess it was a quite skilled performer (although not a world class classical star, some unevenness in the fast runs reveals this, if I may be so bold?!).
From my conservatory years I have quite a few pianist friends, and I have several times enthusiastically tried to show them the latest landmarks of gigastudio sampled pianos, mostly through demos. The only gigapiano I have to play is The EW steinwayB. (Money matters and scepticism have kept me from investing in another one so far). They also picked the right ones in your little sample vs. real contest last year without trouble, and I have not been able to fool them yet with any demo. Until now that is. I think for sure I will get either your lady or the emperor.
-The only place in the demo that felt a tiny bit fake was in the beginning at 0:27 mins. where the pedal is lifted. The stopping of the sound as the pedal is released is too abrupt I think. Maybe I am being to picky here, but once everything else is so perfect, one really start to catch the little details. I don't know if this is a programming issue? I tried adding some reverb from Acoustic Mirror, which helped quite a deal (and, boy was the piece even sweeter to listen to!!!).
-Something else I noticed: At 2:42 there is a single note in the top melody that suddenly jumps to the left speaker, where the rest of the line is in the right side. (just in case you didn't notice, sorry for pointing this out)
