Hello guys i have this script  
using System.Collections;  
using System.Collections.Generic;  
using UnityEngine;  
using UnityEngine.UI;

public class m : MonoBehaviour  
{  
[FMODUnity.EventRef]  
FMOD.Studio.EventInstance Menu;  
private string menus = “event:/Menu”;  
private int pa = 0;  
void Start()  
{  
Menu = FMODUnity.RuntimeManager.CreateInstance(“event:/Menu”);  
Menu.start();  
FMODUnity.RuntimeManager.AttachInstanceToGameObject(Menu, GetComponent(), GetComponent());  
}  
public void btnTest (Button btn)  
{  
pa = 1;  
}

```
void Update()
{
   if (pa == 1){

 Menu.setParameterByName("Filter", 1f);
    
}

```

}  
}

Everything is ok except the setParameterByName  
i have this error  
“EventInstance’ does not contain a definition for ‘setParameterByName’ and no accessible extension method ‘setParameterByName’ accepting a first argument of type ‘EventInstance’ could be found”
