Great post, Nathan. Picking up on a couple of other points from others, I think someone here commented on my Flugelhorn on-the-fly demo as having too much vibrato which wasn't natural for an orchestral piece. Two points on that - first the vibrato is of course optional, secondly I'm a HUGE fan of the Flugelhorn and Euphonium in general and for me they're both going to get some particular love for classic brass band stuff, which imo DOES use vibrato. That's why I naturally lent on it. On vibrato in general, I think it's needed for the trumpets to get some movement in those chords, I think it sounds great on the solo horns and then the Euphonoium / Flugelhorn for band writing, but for most of the rest of the instruments its not really needed. Also I think having Bass Trombones, Tenor Trombones, Cimbassi, Euphonium and Tubas makes this among the very best-covered libraries for low end heft. Most of these go down to C1, also, and several are sampled to very nearly this point. Personally I think I'll be able to live without Contrabass Trombones AS WELL.
