I'm constantly fascinated by the SRX 10 C-trumpet section. It is 100% like a real orchestral trumpet section, except the difficulty to control crescendo/decrescendo during a tone. I haven't heard any classical trumpet section of any current instrument that would come close to that.
What I dislike, and it's audible here, too, is the bad quality of the reverb, it always makes the overall sound a bit acute. Of coure I could have taken some higher frequencies out, no fine-tuning done about it yet...
