Hey, I really do play Saxophone, other woodwinds and MIDI wind controllers (WX11 and EWI-USB).
The reason mention the instruments I own and play, is to say that each and everyone needs to be practiced and played on its own merit. They are all different. That being said the only major flaw with this app is that you can only can put down no more than five fingers at time. A real bummer, and so different from all woodwinds that it really needs to be givin a name other than Saxophone. Other than that, its fun to play with.
