There is not a clear distinction being made between "synth brass" and
"brass", the latter being realistic acoustic sounding brass. The problem is
you're getting kind of inbetween answers. For synth brass, an LP only is
okay if that's the sound you want. There is a bit too much emphasis placed
on the specific filter here though as you can get good brass sounds from
many different filters. For acoustic brass, as mentioned a highpass that
can cut off some of the low frequencies helps, but that's only the start.
You'd want to set the resonance on the highpass to the instrument's main
formant, about 1200-1300 Hz for trumpet, about 800 Hz for trompone, etc. And
there's additional EQ, FM mod on the attack of the notes, animation in
timbre, and velocity,pedal, and/or breath control to vary the sound of the
brass. Refer to my Alesis Ion demos for those techniques, which use the
Moog filter for the LP portion. I also have a very old trumpet demo on the
440 module page on the Synthtech site, and a generic 440 synth brass demo
somewhere else there which were done as initial trials to use a breath
controller with the motm.
