I am trying to wire up multiple LED walls into a Colorsource 20 and I am concerned that I will run out of physical faders for all of my fixtures. Is there a way to patch multiple fixtures into one physical fader. I want to be able to change the colors of our RGB LED strips in batch and record a playback of all the wall colors to one fader. I know how to create playback memories, but I'm worried about not having enough physical real estate. Any thoughts or advice would be greatly appreciated.
