I've thought about this a lot and it is one of the most important topics. Unfortunately, almost no sample users ever do anything about it except "fix it in the mix" (if they do even that which they often don't), It is in sampling that the most grotesque and ridiculous distortions of dynamic range occur.
An example - a solo flute being louder than a trumpet section. This is nonexistent in reality, but no big deal to the average sample user.
I strongly feel that the person doing an orchestral work with samples should use as his guide the philosophy of the great recording engineers of the 1950s, whose goal was to create a single mike placement that would capture every instrument perfectly. This necessarily entailed allowing for huge differences in dynamic range, with woodwinds being almost nonexistent and brass and percussion dominating.
The loudest instrument in decibels in the orchestra is the timpani. The other percussion are the next loudest, and then the brass. All others are tiny in actual acoustic output compared to those. So that if a composer using samples makes his woodwinds match the brass and percussion, he is utterly distorting the acoustic reality as soon as any dynamic above mp is heard. This is similar to close miking of weaker instruments.
One can gain a basic appreciation of the relative dynamic ranges of the various instrumental groups from the traditional sizes found in various orchestral sections. The reason there are dozens of strings is to attempt a match for about four brass instruments. As soon as you add the huge numbers of brass in the Romantic Era orchestra, you are talking about an even greater discrepency.
Another clue to these dynamic ranges can be heard in some great works of orchestral music. Perhaps the most illustrative are the symphonies of Bruckner. His music shows an enormous dynamic range, constantly contrasted in the most extreme way. And the woodwinds essentially drop out when matched against the large brass sections with timpani. The strings are barely audible as well.
So it is a matter of how much you want to contradict the basic fact that the percussion can obliterate all other sections put together, and the brass can easily dominate to the point of inaudibility the woodwinds, and near-inaudibility the strings. If you use dynamics that involve the actual physical capabilites, as opposed to the judicious use of those by a conductor, you are talking about very simple relationships. In a pp all instruments are equal. In an ff only percussion and brass exist. However, we are used to many years of recordings, that nullify those relationships. Play in or conduct an orchestra for a while and you will be reacquainted with them.
So there is no hard and fast answer. It depends ultimately on how you wish to represent the sound in your mix.
