void loop() {
   // put your main code here, to run repeatedly:
   sensor0Value = analogRead(sensor0Pin);

...   
   controlChange(0xB0, sensor0Value, 0x07); // VOLUME

...
}

You basically want to check for a change. For example:

if (sensor0Value != oldSensor0Value)
   controlChange(0xB0, sensor0Value, 0x07); // VOLUME
oldSensor0Value = sensor0Value;  // remember for next time through

Ditto for the others. Of course, you need to set up the oldSensor0Value variable.
