"Free" pretty much automatically means no deep sampling involved, which is why the DSK patches sound like they're straight out of a Standard MIDI collection. But even Big Fish Audio Vintage Horns ($199) library has horrible legato scripting, attacks are way to heavy at all velocities, and really should only be used to double up live tracking to create fuller mixing, if used at all. I play trumpet and trombone on my own mixes so I rarely have issue with brass, but often it can sound so much better to double up on tenor sax...VSL libraries were pioneers in deep sampling, and although their patches can be found on NI KOMPLETE (a great value, even just for having KONTAKT), the memory-heavy legato patches are not included so you're stuck with cheap sustain and staccato patches. Despite it's plasticy sounds in big block chords, NI Session Horns as mentioned above are probably the best of the bunch out there for having more articulations on tap and a really natural brass ensemble panning feel...and sound not too shabby if you understand each instrument's role and can voice the parts in their natural tessatura. BTW if you own a DAW and even just mess about with your arrangements, NI KOMPLETE is still an excellent value in the long run.
