I think professional jazz trumpeters can play quite long forte passages without breathing, using diaphragm breathing you learn when playing brass (don‘t know these special technique expressions in English).
This player certainly didn‘t prepare what he wanted to play and didn‘t optimize it for ultimate realism, but the physical modeling still makes it surprisingly realistic on its own in my opinion. Maybe I‘m unconsciously compensating for the shortcomings of his playing and focusing on what the virtual instrument makes of it, because I’m not interested in judging the player, but in the quality of the emulation. and that‘s certainly more than what any hardware synth/keyboard could do. Unfortunately, it requires the full Kontakt software in order to use it.
