Just for the record, the "sample modelling" products are not related to sampling as the operative word. Yes, it was likely (just guessing really) analysis of samples that produced their proprietary methods. But "modelling", as in generating a model algorithmically, is the operative word.

Apparently Sample Modelling modeled many sonic timbre signatures that are as variable as can be, based on the physical changes that happen during an actual sax, trombone or trumpet note or phrase. Then they wrote algorithms to achieve these sound signatures or change processes.

Pianoteq (a 20 meg program, no typical sample library) also has a real time modelling method, but for pianos and other keyboard instruments. MIDI can be used to play these instruments but each accepts other variables from what i could glean from videos. Pianoteq uses adjustments prior to play that create very distinct intruments.

Sample modelling's offerings are more zeroed in on a particular individual horn, and apparently, allow editing of performance data. But they both probably allow controller access during performance. I am not sure exactly how MIDI or proprietary controllers come into play in real time versus on the piano roll editor of these products. Getting a nearly perfect performance, for horns or sax, might require piano roll editing.

Anyway, if realistic instruments were to be had by basic sampling with loops and simple envelopes, these would be the more boring of the bunch (Why u look at me dis way xylophone? I don't mean to insult you xylophone! Marimba, get hold of yourself.). Even the combination of vibrato rate and depth makes it hard for a sampler to approach violin or cello perfectly. Sax and trombone and trumpet are as hard if not a lot harder since the overtones are varying not as would be reproducable by filtering, but radically, and in contrast to a linear envelope, these changes happen as a player blows harder or forms lips in different direction, which he/she can do early or late in the note or phrase. I really don't know with any certainty or precision about this stuff; if i'm wrong please correct me! But its fun for me to think about which is why i put my 2 ¢ in.

I don't work for a virtual musical instrument modelling company.
