Hi people,

When trying to call a parameter in an event I have a problem with the following lines:

```
FMOD.Studio.EventInstance CarMotor;
FMOD.Studio.ParameterInstance RPM; //It doesn't work (1)

void Awake()
{
    CarMotor = FMODUnity.RuntimeManager.CreateInstance ("event:/Car Motor");
    CarMotor.getParameter("RPM", out RPM);//It doesn't work (2)
}

```

Apparently, FMOD 2.0 uses other methods for that.

(1) Instead of ParameterInstance, the options offered are: PARAMETER\_ID, PARAMETER\_FLAGS, PARAMETER\_TYPE, PARAMETER\_DESCRIPTION.

(2) Instead of getParameter, I get ‘getParameterByID’ and ‘getParameterByName’.

Please help.

FMOD 2.0 introduced a new Parameter API, you can read more about the changes in the [What’s New](https://fmod.com/resources/documentation-api?version=2.0&page=welcome-whats-new-200.html#new-parameter-api) section of the [FMOD API User Manual](https://fmod.com/resources/documentation-api?version=2.0&page=welcome.html).
