    Cue points are records of events that happened during a recording. An event could be music starting, a wrong note, the start of a new page, a false start, etc. The GX9000 allows you to log each type of event as it happens, as a cue point, so that you can quickly and easily find it again. See chapter 12 for a more detailed description of The Take Logging System.
