When I dynamically replace the events in sudioeventemitter, the previous music will be played agpublic

class test : MonoBehaviour  
{  
public Button a;  
public Button b;  
public StudioEventEmitter s;  
public void Start()  
{  
a.onClick.AddListener(()=\>{  
Play();  
});

```
    b.onClick.AddListener(()=>{
        Stop();
    });
}
public void Play()
{
    s.EventReference.Path = "event:/BGM/system/yongyan_theme";
    s.EventReference.Guid = RuntimeManager.PathToGUID("event:/BGM/system/yongyan_theme");
    s.Play();
}

public void Stop()
{
    s.Stop();
    s.EventReference.Path = "event:/BGM/system/lobby";
    s.EventReference.Guid = RuntimeManager.PathToGUID("event:/BGM/system/lobby");
    s.Play();
}

```

}ain

There is currently no way to set the event on a Studio Event Emitter using script, there is some discussion on it [here](https://qa.fmod.com/t/how-do-i-change-the-event-in-fmod-studio-event-emitter-through-c-it-keeps-playing-the-same-previous-event/13928/6).  
You can try adding a method to the FMOD Studio Event Emitter that sets a new event:

```auto
// Assets/Plugins/FMOD/src/StudioEventEmitter.cs
public void ChangeEvent(string newEvent)
{
    EventReference = EventReference.Find(newEvent);
    EventInstance.stop(FMOD.Studio.STOP_MODE.IMMEDIATE);
    Lookup();
}

```

```auto
// test.cs
public void Play()
{
    s.ChangeEvent("event:/Music/Level 01");
    s.Play();
}

public void Stop()
{
    s.ChangeEvent("event:/Music/Level 02");
    s.Play();
}

```

The recommended approach is to create your own script. You can can take a look at how to call the FMOD Studio API yourself in the [Unity Basic Scripting Example](https://fmod.com/resources/documentation-unity?version=2.02&page=examples-basic.html).
