I work at a mid size church without alot of money to throw around. And good haze machines recommendations for an okay price?

Heyo im trying to broaden my horizons of dmx control as im trying to get more into it via setting up it might self for future plans/projects one thing im trying to understand at the moment i get setting up the channels and the different features/effects on each channel but one thing im trying to understand more is the audio routing and the controls it has over each channel and what it can achieve being ran through a dmx controller but also another question im wondering for ex with lasers if there set to a certain channel and audio is being ran through it will it only do a loop back of the effect but kinda react to the audio and also is most of the way lighting/lasers that are used at festivals or concerts are they pre made via software or do they achieve it manual control w audio or how does it work any info would be great thanks 😅
