Near the end, when the saxophone (wrongly titled trumpet at that point) makes a legato from D to G (at about 5:29), I am sure this legato cannot be done without modeling features. It's not just a legato like in the Motif, where the attack phase of the sample is just skipped (by scripting techniques).
This would mean that there is a form of SA2 voices in action.

The piano as well as the Seatlle String section sound truly outstanding. (The small section, well, I never liked this uniform vibrato very much.)
