Here's a folder of some quick and dirty tests.
On all long notes, I'm using a breath controller for dynamics. Vibrato is on the wheel with CC1. Dynamics for short notes are CC1 controlled.
Onboard reverb and fp hall setting are both off. No additional anything. I just turned up each Kontakt instance from -6db to 0.
In the Harry Potter excerpt for full brass, I decided to give the three trombone parts to the cimbasso instead, so that could get some air time, and also because there are no solo trombones in the basic version.
The legato could be more agile in places, and I would love to not have to simulate re-tonguing with the breath controller. Those are really the only critiques I have at the moment. Exposed and unprocessed like this, I think it's holding up brilliantly.
I'll explore more later, and try some "flashier" parts.
