Paint Music Application not working properly

Hi,
I am trying to develop a Paint music application. This is how it should work, when you draw any stroke it should play the sound associated with the color and should play continuously. Every time when you make a different color stroke it should play some piece of sound. Currnelty I am only using primary colors but needed to be extend for more colors.
Here, I am not using any external file (any wav or mp3 but this is the idea) and using sine wave sound generator function. I have tried to do the same but it is not working properly
I also wanted to control the volume but it not happening too.
