Nick we have compared the sax from the three you mentioned already...even a SZ comparison that most thought the G1000 sax sounded better[a SMF was used for the test..]and the Roland's were not tweaked..Other 's tweaked the Tyros2 to include the best they could muster out of the Yamaha...The vast majority including Yamaha supporters agreed ..Matter of fact we used several sound sources and If I can recall the Tyros was sitting in 4th or 5th place of the test...You can search Dogget..

Since this test as you know I tested the G70, and one of the sounds that impressed me was the sax..I use the breathy sax anf EXp sax on the G1000..These are my favorite saxes with the exception of the new G70 sax I played..
