My bad if you were exclusively talking about VSL's natural volume. It's true that I kindof expanded the subject without warning ^^.
To Dominique:
About the dynamic range, I explained that my data is regardless of the note, meaning each time the softest equals the ppp of the softer register, and the strongest is the strongest of the stronger register. The result is a data not depending on the register you play, but it doesn't mean that your instrument will be able to reach that particular volume with every notes.
As I said, using the xfader at least, the vsl instruments I use are not completely "normalized". They have strong and weak registers already, and with a little tweaking on the dynamic range scaler, I can have some "realistic" behaviours on the whole dynamic range without having to think about it anymore. Of course, i'm sure it's not perfect, but it's more than close enough.
And for my winds and brass, which are all sample modeling's, once you set up correctly the dynamic range, since they are semi synthesis, they behave naturally already, with credible changes in the dynamic range depending on the register. The main purpose of my whole method is to set a "global dynamic range" on the instrument, to be able to balance it with the others. If internally, the instrument is unbalanced with itself, it won't be fixed. But in my experience, it's not the case.
One thing I didn't mention : I think this whole method became necessary because I combined several different libraries, which I had to balance intelligently. I guess VSL products are more or less balanced within themselves, so with a "Only vsl setup", it might not be as useful. Don't know for sure, though.
on the "Tchaikovsky" aside^^: I'm not convinced. Noting something so far from reality that it is not fisible (if i'm correct, many if not all orchestras switch that bassoon for a bass clarinet) is not "ideal", it's a mistake^^. Maybe Tchaïkovsky bet on future enhancements on the bassoon so that it would be able to get softer, i don't know. But on a score, if something is not practical, it's not "ideal", it's "not good" ^^. Please keep in mind that I know who we are talking about, one of the greatest composer of all time, whose work is purely astonishing. He's personaly one of my favourite composer (if not THE one), so i'm not at all making a point "against" him.
