Sorry for the extra post. I submitted my responses from home (I'm at work now) and for some reason they did not post. Not sure why.
On Brandon Fields, I have his release "The Traveler" and on it he actually plays a Yamaha WX7. It's apparently a variation on the EWI or EVI and is sometimes called a WX7 saxophone.
Another instrument I love is the guitar synth ala Pat Metheny. He's been using it for much of his career with the PMG and keeps improving in its use. You hear it on Metheny group classics like "Third Wind" (The Road to You); "To the End of the World" and "Red Sky" (both on We Live Here), as well as many others. Saw Pat and the PMG in concert last year in what was the greatest music/jazz experience I've ever experienced. He used the guitar synth liberally that evening.
