I edited this post to be a slightly more substantive, though it is probably no longer needed. I agree that the only criticism about the VSL would be that it is a work in progress, in that the only things lacking are things that have not yet been completed, i.e. the vibrato oboe, some missing forte legato, etc. The cross-faded dynamic layer instruments are an essential way of getting a great deal of mileage out of very few separate files, when combined with the staccatos, and the legato tool is a unique invention in sound.
I also have not used the repetition tool much yet, as it is definitely not intuitively obvious, though it is an example of the subtlety of sound that this library excels in because of the difference - slight but noticeable - of rapidly alternated single note samples and multiple notes recorded while the instrument is still "vibrating" from the last note played. It would be possible to have five single note samples on the alternation tool, but the effect would be a "representation" of the effect, not the exact effects itself.
