Hi everyone!

I am using the addCue method on a p5.soundFile. I invoke this method in the setup function. The callback function i provide is called multiple times (around 170) instead of just 1 time (which I expected). Does anyone know more about this? I know I can add a check myself so the critical part of the callback only runs once, but this seems a bit tedious.

Thank you!  
Casper

Hello @casperleerink!

I think you have to share some code with us; it’s hard to see what’s going on without it. But, could it be that you’re looping the sound so that the cue point is reached more than once? From the [`addCue()` documentation](https://p5js.org/reference/#/p5.SoundFile/addCue):

> Schedule events to trigger _every time_ a MediaElement (audio/video) reaches a playback cue point.

Emphasis added by me.

Hi Sven,

Thank you for your reply. I don’t think i’m looping the sound. Here is the simplest version which produces the same unwanted result:

libraries:

```auto
<script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/1.0.0/p5.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/1.0.0/addons/p5.sound.min.js"></script>

```

```auto
let audio;
let cueCount = 0;
function preload() {
    audio = loadSound("assets/audio/storm.mp3");
}
function setup() {
    createCanvas(400, 400);
    audio.play();
    audio.addCue(2, cueCallback);
}

function cueCallback() {
    cueCount++;
    console.log(`Callback is called: ${cueCount} times`);
}

```

running this code on my live server calls the cueCallback 173 times

Funny, looks like you stumbled over [a bug that was actually fixed](https://github.com/processing/p5.js-sound/pull/449) just a couple of days ago. So you can look forward to this issue disappearing in a future release of the library. 🎉
