A little improved.

This is Alto Saxophone.
I made the application assuming that the app play with Surface Pro.
*I don’t recommend playing with iPhone due to playback sound delay in iOS.

[control]
This app uses 9 buttons (same fingering as real saxophone but less than real) and acceleration that act as octave key (left hand thumb).
In order to be able to play as easily as possible, I did not implement the fingering that I rarely used.
Since the value of Acceleration changes by tilting the Surface, it is controlled using it as follows.
Not tilt: NO press octave key
Tilt: press octave key
In other words, the sound keeps while tilting the Surface like the video above.
In the case of Surface, it used the value of the Y axis of Acceleration to play like the video above.
But depending on the device, it may necessary to change the axis of accerelation and the threshold of tilt if you use the application.

I use the free saxophone sound file obtained from the website below (University of Iowa Electronic Music Studios).
