I wonder if it would be possible to start the show from the point it would be in at the given point in time. It appears that the slave is able to do this when the conductor sends it the start and timing data. I know that it is not as easy as it sounds but is that a possibility? If the Cnductor also knows how long the show is, when starting up it could look at the previous show and determine if that show should be currently running. If not, then it waits for the next scheduled show and if so, it can scan thru the show file looking for the point in the show where it should be and start the show from that point. If you were to connect the Conductor to a UPS and a power failure were to occur, the Conductor would have no idea and would continue to run the show. When the power returned, the lightss would continue at the point in show time that the power returned so there would be no difference in looks.
