Bravissimo! If there is any demonstration that has convinced me of the value of the Syncron approach, it is your Holberg simulation. It is the best of its kind I have heard anywhere. You should give classes on orchestral simulation.
I agree with most comments made by others, but I take a different perspective. The sharpness, clarity and "fattiness" of the sound here are such a welcome improvement in sampling. I've spent hours trying to imprint these qualities in my simulations, with very mixed results. It will be easier, I think, to shave off and blur the sharpness than it was to improve the sharpness of more sloppy sounds. To use a cryptic formula, it's always easier to do less with more, than to do more with less.
A last note: I have never heard any simulation that could really stand up the comparison with a top notch orchestra. In this case, I listened to Karajan directing the Berlin Philharmonic in the Holberg Prelude, and I must say that your simulation held up very strongly. Not perfect, OK, but extremely convincing, with a sound envelope that is very dense and lifelike. Now, the challenge is to humanize and blur the contours, an easier task than trying to make blurry stuff more incisive. Once again: bravissimo!
