Do you have the full NI woodwinds or just essentials? NI has a soloists pack, too, whereas Sonokinetic's is just ensembles, so that's a potential difference. I've been trying to figure out how many dynamic layers the Sonokinetic instruments have. My sense is that it doesn't really reach into ff territory much less louder, but maybe I just missed the demos that illustrate this. I only have the essentials for NI winds (they came with KU11), and haven't done anything but play them a bit, but they also does not seem to have the forced tone of the higher dynamics (in order to maintain consistency of tone I imagine). The ensemble is generally tighter in the NI essential patches as well. As I mentioned above the looseness and tightness of the ensemble is a bit of a taste thing, but the looser ensemble might have worked well with, say, the Arks if the the Sonokinetic ensemble winds just weren't so darned polite!
