Just heard this and read the concern of the sound and wanted to add my two cents worth.
Many people have an opinion of variouos types of music and also have preferences. I thought the violin sounded perfect for the piece. it sounds very balanced in the style it was rendered. I love VSL instruments and try to use them even in non-classical music because they are so realistic.
Perhaps the critic tends to like more "gypsy style" violin, or something with a LOT of expression. I have 8-10 different violin libraries and the producers can't make all libraries, everything for everybody. They have a goal in mind, and sample towards that goal.
One of my libraries has a weepy sound and would be good for that kind of music. Another is more expressive, and would produce a sound more like a Hungarian Rhapsodie, Another is perfect for Gypsy violin. And another, and another, and...
I'm guessing the critics have their favorite genre, their favorite "violin sound" and don't appreciate other types of music and performances.
VSL's goal was to come up with the biggest, the best, the most complete, and the most natural sounding "entire orchetra library". Had they done "one offs" of each peice in an orchestra, it wouldn't sound natural when combined.
I wouldn't worry about it. Did they offer a piece of their music in the same style, with what they believe to be a more realistic rendition???
