Hello, for my high schools spring musical (Cabaret) we are renting an ETC Ion console. Along with the board, we are renting scrollers and some movers. I have learned how to patch a scroller into the same channel as a dimmer (By adding a second part to the channel, and adjusting the channels type from dimmer to scroller) but some of my dimmers have more than one light that each contain a scroller. For example, area A has four lights cabled to the same dimmer, and each of those lights are equipped with a scroller. I will not be receiving rentals for a week or two, so I have been soft patching my show beforehand using computer software. I have taken area A's channel and added four more parts and assigned a scroller to each part, and when I enter the channel and try to control things, it seems that I have no choice but to control all of the scrollers at the same time. Is this the only option besides putting each scroller into its own channel and controlling them one by one, or is there something I'm doing wrong? Also, the issue might have arose due to the fact that I don't actually have the board, nor control of any lights at this point, if so, please inform me. Thanks in advance.
