Large control systems have the ability to alter channel levels through out the memory range. Simpler controllers (as used in permanent installations) tend not to so if a fixture is changed the entire plot will have to be re-recorded. The Grand Master can get around this problem by limiting or boosting a changed fixture’s level through out the entire plot.
