If you want to emulate acoustic and acoustic/electric instruments like sax, trumpet, guitar, etc., you have only one great choice, the Yamaha VL70-m.

I've been playing wind synth since the 1980s and have played my WX7, WX11s and WX5s through a number of hardware and software synths. The VL uses physical modeling and actually feels, responds, and sounds like you are playing a physical instrument instead of a synth. Other synths might have a little better tone, but the tone is not as flexible and the expressive capabilities pale in comparison.

There is also an aftermarket TURBO chip that provides better tone for many patches and a wide assortment of guitar tones ranging from Flamenco to Hendrix. http://www.patchmanmusic.com/turbovl.html

Check out the clips at http://www.nortonmusic.com/clips.html for some lo-fi demos.

The most unfortunate thing about the VL70m is that after a 15 year run, they have been discontinued by Yamaha. Matt at Patchman Music often has used VLs for sale, and you might be able to find one at Ebay.

I like them so much I bought two.
