Mark,
Trumpet is one of my favorite instruments, the second is piano. There keyboards that will give the trumpet many different sounds using the after touch and added buttons --- but I have not found a trumpet that sounds more natural than the one on the Technics keyboard.

In my Kn7000 I created eight different trumpets to meet my different needs. Strong with little vibrato, soft with a gentle vibrate, high with a very strong vibrato, ect. Keep in mind that although keyboards have come a long way in duplicating instrument sounds they still run short when compared to the real thing. And all of it is still a matter of personal taste.
