Make dmx strobe and Lighting sound on speaker on a button

Hi,
I know a average amount about electronics. I run a community weather website and also setup for events.
On saturady last minute we are having a marquee setup an evening event and want to make some fun for the kids.
What my idea is to have a button that the kids press that then makes my strobe light flash for 1 second while playing a lighting strike and bassy boom after.

I hav a pa active speaker which is fed by a mixer.

Is this possible?
I do have a rpi zero board if thats any use?

thanks
