it seems that you are looking for the real thing.
This will never happen because it is simply impossible.You can get close to it, but you can't expect a perfect simulation from any sampling company.And as a performer I have to say that I am glad about this fact.
Well, I'm sure most companies are aiming for the real sound, if not they wouldn't put so much work in this.
Imho in discussions like that arguing with the "real" thing seems to be a more or less esoteric matter:
Do you really want "the real thing" so be ready for all its "real" shortcomings. In reality there are very much orchestras only very few of them do really sound as excellent and brilliant as we do expect it from the predominance of recordings made by the most oustanding Orchestras. (Not to mention how tedious it is to realise with a more or less average orchestra conseqently what your musical imagination might inspire.
On the other hand samplelibraries are part of our current reality, it seem to me a bit unrealistic to dispute them their reality. However their individual problems and potentials might be.
Having said that I am not interested in arguments based on any more or less idealistic understandig of what ever some one believe he must demand the "reality" should be. What I am looking for are "good" samples, what means samples which allow me in the most convincing way to realise musical ideas. I am quite optimisitic that the VSL-Experience is a pretty good fundament to create musical reasonable and versatile samplelibraries. For me they already belong to the by far most convincig with what they have done. And if they need the time to keep their high quality standard, I am happy that they do nothing in any premature way, this is what I do expect most.
