The T-Bar lighting serves two purposes. The light color denotes the delegated source it is controlling at any moment – green for LIVE, blue for the CLIP LIST, and gold for the PLAY LIST. Normally, the light is brightest at the top of the T-Bar’s stroke, representing 100% playback speed. At the opposite extreme of T-Bar travel, the light is noticeably dimmed. In +/- operating mode, the light is dimmed at the mid-point, representing 0% speed (playback stopped).
