Tony, I think it's really difficult to get a good sax simulation without some kind of breath controller; better yet, a complete wind controller (with/without built-in sound module) such as the old Yamaha WX5, the Akai EW4000s/EW5000, or Roland AE40G). It's not the tone so much as the subtle dynamics of the sax that is so hard to capture. Of course, if you get a wind controller, you still need to know sax fingering. I know sax/flute fingering and I have thought many times about getting a wind controller, BUT, I figure, if you know how play sax, why not just play a real sax into a good mic.

Of course manufacturers will continue to try to make more authentic sax sounds on keyboards; now, they just need to figure out how to get keyboard players to think and play like a sax player.
