With a keyboard pitch bend causes no problems, because it is held at center. The timbre sounds about right to me. I gave it a slight peak at 1100 Hz, as I read that many trumpets have a peak there, and the brightness and upper partials give it about the right sound to my ears through all octaves of a trumpet. The Dynamic Filter was set up with a low pass filter that emasculates the highs and the sizzle at low pressures, but it is pulled off by Breath Pressure to give it full brilliance in the top two octaves. This is similar to a real trumpet, and you can sound like you have lips of steel by simply blowing a little harder.
Tongued notes have about the right attack.
You can tongue very quickly and get good staccato attacks. Try blowing at constant high pressure and finger some notes and you will see the characteristic that it has. If you set all of the attacks to 127, the Note On will generate harsh attacks, which you have to be careful of during fast play. You can still play fast with sharp-tongued notes and get sharp attacks, and you can do fast trills about right. If you want the full sharpness, just set both attack rates to 127 and the first level to 127.
