Playing sounds on the VEX IQ

I built a drag racing Christmas tree using 4 led touch sensors. I want to play a note each time the light changes, but I can't get the VEX IQ to play a single note. Instead the note repeats 9 times. Honestly I don't fully understand the code to create the note. Please help!


	Code: TMusicalNotes nNoteToPlay = (3 << 4) + 5; //3rd Octave, Note 'E' playNote(nNoteToPlay, 30); //Play the note for 300ms

Here is the full program. I don't have the sound playing after each light change yet. It just plays at the beginning.


	Code: #pragma config(Sensor, port1, redLED, sensorVexIQ_LED) #pragma config(Sensor, port2, yellow1LED, sensorVexIQ_LED) #pragma config(Sensor, port3, yellow2LED, sensorVexIQ_LED) #pragma config(Sensor, port4, greenLED, sensorVexIQ_LED) //!!Code automatically generated by 'ROBOTC' configuration wizard !!// task warningSound() { bPlaySounds = true; nVolume = 4; TMusicalNotes nNoteToPlay = (3 << 4) + 5; //3rd Octave, Note 'E' playNote(nNoteToPlay, 30); //Play the note for 300ms } task lightTree() { setTouchLEDColor(redLED, colorRedViolet); sleep(2000); setTouchLEDColor(redLED, colorNone); setTouchLEDColor(yellow1LED, colorYellow); sleep(500); setTouchLEDColor(yellow1LED, colorNone); setTouchLEDColor(yellow2LED, colorYellow); sleep(500); setTouchLEDColor(yellow2LED, colorNone); setTouchLEDColor(greenLED, colorGreen); sleep(2000); setTouchLEDColor(greenLED, colorNone); } task main() { while(true){ if(getJoystickValue(BtnRDown) == 1){ startTask(warningSound); startTask(lightTree); } } }

Thanks,
Joe
