No, the VSL Cornet is one of the great sampled instruments. It is molto espressivo and the ultimate performance and recording quality.
However, I do agree that the concert/symphonic band could be an area where VSL can create a very unique sound. The large number of clarinets and flutes, trumpets, cornets, and some specific instruments now available allow a clarinet ensemble of 5 Bflat, Eflat high clarinet, alto clarinet (bassett horn), bass clarinet, contrabass clarinet, 5 flutes, piccolo, (not to mention alto and bass flutes), all the saxes in solo versions, 5 oboes, (not to mention two English horns), 5 bassoons, contrabassoon. So what is missing in woodwinds is another massed ensemble of clarinets - perhaps six. Because if you use transposition/pitch shift then you have at least two doublings of each group. This would create a huge concert band sound in woodwinds.
On Brass there are: 16 trumpets in the high range - 6 trumpet ensemble, 3 trumpet ensemble, c trumpet, B flat trumpet, Cornet, Dimension trumpets, not to mention bass trumpet, piccolo trumpet and flugelhorn. In horns there are way more horns than any concert band I ever played in - 18. There are also 10 trombones, euphonium, 2 tubas. Those are the sounds that already exist. But there could perhaps be sampled additionally a Sousaphone as well as the bigger clarinet ensemble. Perhaps there could be a "Special Brass and Woodwinds II"?
