Yep, that's the beauty of DMX - just string on any additional fixtures and the data will pass just fine. Your DMX Operator Pro isn't really an ideal board to control LEDs with, but from a technical perspective it'll definitely work. Good luck!
Thanx for the advice.
I know that my lights are archaic/basic...but at least I have
something. There is a local DJ that rents my PA for his bigger jobs. I'll see if I can borrow a few of his LED fixtures and daisy-chain them to see what happens.
I am hoping to eventually go true LED at some point but as it stands, with the pandemic and all, there isn't a pressing need for me to invest in a current light rig.
If a short-term gig comes up that requires
real lights, I will rent/subcontract as I have done in the past.
