I would add that the performance tool with legato has NEVER BEEN DONE in any form whatsoever. All legatos previously have been faked or non-existent. This is the first time ever that it is real, and as I said in another thread, legato is probably 50 to 75 per cent of musical expression. If you don't have that, you don't have true expressiveness. In fact, you don't have what the instruments really do in a basic way.
There are other libraries out there with tons of samples - Dan Dean, Garritan, etc. but nobody else has this crucial element of music.
Before the VSL came along I was wracking my brains about how to program it. I could figure out how to break it down musically and sample it, and was planning on doing it, but the programming was the stumbling block. And they have solved that brilliantly.
I've been listening to more of the samples (I still have to absorb them for a while because it is an incredible wealth of sound) and they are so beautiful that the addition of legato will truly make this as musically powerful a sound as any number of live orchestras you could hear, let alone get to play your music INSTANTLY.
