So I had a crash course to run lighting for our church today. I had to do service as our LD is sking and didn't bother to train someone avalible to do it. There are 3 people, but 2 of them were on a ski trip and one is an actor who had obligations at a play practice. Anyway All went well except I put my clip board on the light board [ETC Express 48-96] and the clip board hit some bump buttons on the bottom row so some house lights went from about 10-20% to 100. I think it was anywere from 1 to 6 buttons, but I got off of them so fast I didn't have a chance to find out. Anyway I don't want that to happen on sunday. If I put the board in blind mode that can't happen right? If that won't do it is there a really simple way to turn bump buttons off? I'm a n00b to this console and lighting in general, so I figured I would ask the people who would know. I'll probably check it out sunday morning, but I would like to as first.
