Well this one just happened this week. It seems one of teh band helpers, not even a teacher. Came into the Auditorium and messed around with the LCD touch display and turned on all the lights in the auditorium. Including the Source Fours with the four-runner scrollers. Well he did not turn on the forerunner box. Thank God it was only for a short time before somebody on crew caught the mistake before the gels were not ruined. That would have been like $79 per colorscroller which would have been costly.
