How do I use Particle Event Generator in a blueprint?

I have a particle system that has a pulsating orb every so often. It’s a bit random. I want to play a sound every time this orb pulsates. I am told I need to use the Particle Event Generator which I have on the particle system but i’m not sure how I can actually call that event and use it in a blue print.

To be clear the particle system component is IN the actor blue print already, but I just can’t seem to find a way to say “whenever this pulsates, play this sound.”

Thank you so much in advance :).

I too would like to know this.

The documentation doesn’t say anything on how to actually use it, and this question from over a year ago asks the same thing:

As does this forum post that didn’t get it answered either:

In fact the Event Generator docs are pretty sparse when it comes to doing anything more complicated than a simple event generator → event received/response setup for bullets and impacts or something like that.

If any Epic Staff sees this I would like to request an update of this doc to make it more comprehensive:

Nobody :(? There are so many people who have run into this issue.

I have a hunch that maybe because the next version of cascade might be nearby, they might be ignoring particle related issues for now. Niagara is supposed to be much better so maybe we need to just wait for that then.
