The Yamaha saxes, even the Tyros, have fallen behind, in my opinion. The Ketron X1 had a very believable sax, if you played it as a sax player would. I find myself simply not using the sax as much, which to me is no problem. The Growl Sax on the Tyros is pretty good in the right context.
Love those Tyros guitars though.
I am still looking forward to hearing the Genesys in person.
