Jerry,
Like you, my first and primary instrument is classical trumpet. I think that we agree that most sampled "natural" instruments leave a lot to be desired. If that's the case, I really recommend you looking into Gigasampler. I have the Gigasampler 64 and the sound quality of what's available is incredible. My warnings about the need for another computer is for a "best-case scenario". In reality, Giga can work on the same computer as the digital audio sequencer. I have Emagic, a program which doesn't like to talk to Giga. Actually most of the major digital audio sequencers have a problem talking to Gigasampler. A Giga user and programmer created a small shareware "fix" that allows problematic programs (e.g. Logic, Cubase, Cakewalk, etc) to "talk" to Giga and be run on the same computer.
For what you want, it seems that Gigasampler would be the only real choice. Because Giga is probably the closest thing to the real thing that we have today. This is because Gigasampler/studio streams the sample directly off the hard disk rather than the RAM, like all of the rest of software samplers. Thus, the samples can be as long as you like, with no need for a sample to ever be looped to extend its decay. Thus, more realism!!! The Gigapiano that came with my Gigasampler is absolutely amazing. Further there are a few superior orchestral sample CD sets like the Miroslav Vitious Orchestral Libraries, East West's Advanced Orchestra, etc... Despite the high costs of these libraries, you could buy Giga sampler and an Orchestral library, some RAM and still pay less than you did for the Virtuoso.
My suggestion is that you take some time to research Giga products. Even it that only means getting the Gigasampler LE for $80. You could always upgrade later and I'd be willing to bet that you would say that it's the best $80 that you have spent in a while. Truth be known, it actually costs LESS to buy Gigasampler LE and upgrade through the Nemesys website than it is to buy
Gigastudio 96 or 160 outright. Bizarre, isn't it? I hope that you find something that you can use. BTW, Gigasampler is sold by Nemesys at
http://www.nemesystech.com. I don't work for them. Just a very satisfied customer! (that is, once I got through the initial headaches of getting Giga to work with my sequencer)
