Mike.....I think keyboard emulation of real instruments has actually come a long way in instrument reproduction. What HASN'T come "a long way" is the player's technique.....learning to play the characteristics of each instrument that the keyboard so faithfully reproduces.

I've seen so many players, when playing wind instruments, fail to use their pitch bend, vibrato, portamento, and, most important, remember to take "breaths" between notes. i.e. they play all "instruments" like they're playing a piano.

The keyboard can only do so much in trying to "fool" the listener. The rest of it has to come from the player!
