Q Light Controller+

I tried to search the form and haven’t been able to figure out how to do this.
Basically, I have 10 lights that I would like to all flash randomly together as a scene simulating lightning so I guess it would be like a super fast, double blink or triple blink , but I want it every so often maybe no more then a few times a hour .
At the same time i want to set the 10 lights to be a dim purple .

( obvi this is Halloween party prepping lol )

In order to help you, you have to give us more details of the lights you have, what version of QLC+ you use, what operating system and if you can share your project with the scenes you have created for your lights. It will allow us to guide you on how to do what you want.
Without knowing anything about your equipment, I can advise you to do tests with a chaser or a sequence, to achieve the effects you want.
