Hey you guys,
I’d like to listen to parameter changes in real-time (playing the scene) in unity via the “Initial Parameter Values” section. How could I go about doing this?
I’ve provided a video to best explain what I’m trying to do:

I appreciate your help!
\*Also, sorry for the big grey box blocking the game-play visuals. Can’t share that content ☹

The initial parameter values are only set each time the event is played.
Changing the parameters in real-time can easily be done in code.
You are able to get a [ParameterInstance](https://www.fmod.org/docs/content/generated/studio_api_ParameterInstance.html) reference from an EventInstance and call setValue to update the parameters in real-time, see [Triggering Parameter Changes](http://www.fmod.org/documentation#content/generated/engine_new_unity/paramtrigger.html) for more info, or by using the StudioParameterTrigger script included with the Unity plugin.
