Adjust Custom Radio Station Volume

[c0c0c0]

I've got a custom radio station and I'd like to expose an MCM control for users to change the overall volume to their preferences so that it better matches their other stations. It's easy enough to get the volume setting into a global, but what should it be a applied to, and how?

I saw this in the documentation:

int instanceID = mySFX.play(self) ; play mySFX sound from my self
Sound.SetInstanceVolume(instanceID, 0.5) ; play at half volume

Would something like that be applied to the transmitter instance? To each individual track? To the Pipboy itself?

 

Any clues would be appreciated.
