Volume Change Souncipher library?

Hello,

for a Project on my university i do have to create a music instrument with the help of arduino and processing.

What i want to do is a Processing sketch, which will get values from the arduino and change them into music.

As a special thing i do want to change the value of the Volume with the help of a distance sensor.

Here is my sketch:
1. import arb.soundcipher.*;
2. import processing.serial.*;
4. SoundCipher[] sc = new SoundCipher[9];
5. int portValue = 9;
6. int octave = 160;
7. Serial port;
8. void setup()
9. {
10. for (int i = 0; i < sc.length; i++)
11. {
12. sc[i] = new SoundCipher(this);
13. }
15. println(Serial.list());
16. port = new Serial(this, Serial.list()[0], 9600);
17. frameRate(20);
18. }
20. void draw()
21. {
22. while (port.available() > 0) {
23. portValue = int(port.readString().substring(0, 1));
24. print(portValue);
25. sc[portValue].playNote(octave - (portValue * 7), 100, 2.5);
26. }
27. }
Now my problem is, that i have no idea how to change the volume, everything else is working without problems.

is there any easier way than working with CONTROL_CHANGE from soundcipher itself, because i do not get how to work with it.

Would be great to get an answere! :)

Thanks
