I think the N1X external recording benefits a lot from the additional compression. There's so much noise in that recording. I could have made it better if I had a clue what I was doing. I took the video recording (there is more than one video version that goes with these), removed the audio into a wav, then normalized that in audacity (the only way I know how to make it somewhat presentable). Then I exported that wav to mp3 in this most recent upload. I think it makes for a good comparison of all 3. The VST versions came from cubase as wav files but I still did a default normalize in audacity for those. Then the same mp3 export to reduce the size.
I'm also reviewing your original post again and will try your garritan midi file in my own preset. Yours sounds amazing so I might want to try it (not sure if you posted it anywhere). Also, I never would have guessed the first one was pianoteq since it sounded way better than I expected.
I would run it through Ivory 3 if I knew how to render the midi file through cubase. Same with Modern D, I don't know how to do that. I only know it in the Aria player for Garritan, so I always record the Modern D performance through cubase as I play it and that's what generates the midi file which I render in Garritan. I previously did it the same with with Ivory 3. Some of the Modern D performances suffer from this since I can't respond to that piano's behavior. The garritan suffers a little less because it's a similar piano behavior to the N1X CFX.
