I can’t see any of my local parameters in the Unity ParamRef browser. Is that by design? Is there any way to see their names from unity’s editor?

Just to clarify- are you doing something like:

```auto
[FMODUnity.ParamRef]
public string myParam;

```

and asking why you can’t see local parameters? If so, the `FMODUnity.ParamRef` attribute is intended to be used on [global parameters](https://www.fmod.com/resources/documentation-unity?version=2.02&page=api.html#global-parameters). This does make sense as a limitation because if you could see local parameters globally, they would no longer be local. A good way to see which parameters are available on which events, and to audition them within the Unity Editor, is to use the [Event Browser](https://www.fmod.com/resources/documentation-unity?version=2.02&page=event-browser.html).

Oh awesome! I wasn’t aware of the Event Browser. I’ll just use:  
EventManager.EventFromPath();

And then read the local parameters from there. Thank you!

Hi Jeff. So how can we create a refference to the the fmod local parameter to use in code if we can’t use [ParamRef] ?

You can get a list of event-level parameters by calling `EventReference.GetEventDescription` on a Studio Event Emitter instance to get the underlying `EventDescription` object, and from there you can get a count of parameters using [`EventDescription.getParameterDescriptionCount`](https://fmod.com/resources/documentation-api?version=2.02&page=studio-api-eventdescription.html#studio_eventdescription_getparameterdescriptioncount), and iterate over them using [`EventDescription.getParameterDescriptionByIndex`](https://fmod.com/resources/documentation-api?version=2.02&page=studio-api-eventdescription.html#studio_eventdescription_getparameterdescriptionbyindex) to build up a list of [`PARAMETER_DESCRIPTION`](https://fmod.com/resources/documentation-api?version=2.02&page=studio-api-common.html#fmod_studio_parameter_description).  
From these parameter descriptions, you have access to their names, min-max values etc, which you can use to pass into [`EventInstance.setParameterByName`](https://fmod.com/resources/documentation-api?version=2.02&page=studio-api-eventinstance.html#studio_eventinstance_setparameterbyname).
