Hey,
First up let me just say that I'm not a real lighting guy, I'm an AV tech who does lights so I apologise for the holes in my knowledge of lighting!
We have been using Hog 4's at my work for a while now and I'm trying to work out a way to make our Chroma Q Color FOrce 72's strobe randomly.
I'm running the lights in Mode 4 which means each fixture has 12 cells of RGBA so with 7 fixtures we have 84 cells in total and this seems to gives us the best control overall.
I tried to edit the patch in the fixture builder and just add an intensity strobe control to each DMX channel and assigning the control as rate instead of shutter, however this just acted like an intensity control and didn't make anything strobe.
I'm sure there's a million ways to do this so hopefully a real lighting guy can help!
Cheers
Nick
