Hello, I have several pieces of BGM and I want to switch from one to another. How should I do that?  
I have tried change the eventinstance of emitter but it didn’t work.

Thanks.

Hi,

What version of FMOD are you using?

How are you playing the first BGM event? Could I get a code snippet of how you are trying to change events?

Fmod version is 2.02.11.

I set up event in the inspector and control it in Start method:

> private void Start()  
> {  
> musicEmitter.Play();  
> isPlaying = true;  
> }

Here’s my ChangeMusic method:

> public void ChangeMusic(string eventName)  
> {  
> musicEmitter.Stop();  
> musicEmitter.Event = eventName;  
> musicEmitter.Play();  
> }

Hi,

`Emitter.Event` has been deprecated and won’t change the event the emitter will play.

I would recommend making a public list of emitters:

```auto
public List<FMODUnity.StudioEventEmitter> emitters = new List<FMODUnity.StudioEventEmitter>();

```

You can then iterate through to start and stop:

```auto
emitters[0].Stop();
emitters[1].Play();

```

Let me know if this works for you, there are some other options too.

Hope this helps!
