[Using ETC Element] I am trying to program an effect or a series of linked cues (can't figure which is a better approach) to simulate a train passing across the stage. I have 2 old Technobeams (mirror fixtures) and 2 MAC DesignSpot 250. The idea is to have them each sweep straight across the stage (in my case SL to SR) in a straight line, fade out at the far edge, reset to the opposite side of the stage, and sweep again. I want them each to sweep at their fastest speed, and not all synchronized (they can't all start at SL at the same time or it will look funny). This whole sequence should loop a couple times and then fade out. In a perfect world they might strobe a little along the way). Of course there will be some conventionals on throughout this from the previous and next cue...so the existing "look" should remain unaffected. Any ideas...reference instructions...pointers? Thanks!
