Pushing PLAY initiates playback of the currently selected source – whether a clip in the CLIP LIST or PLAY LIST, or a Delayed video source. Pressing PLAY when a clip has stopped its last frame replays it from the beginning. When a newly delegated source is at 0% speed – whether due to pressing STOP or T-Bar use – the initial T-bar position is ignored when you push PLAY; playback is initiated at 100%.
Tip: For Live video sources, all transport control operations are invalid when REC (Record) is disabled, and will have no effect.
Note that you can press SHIFT + (Play) to toggle the playback Loop setting (the loop control in the playback control group beneath the monitor for output B lights to shows when loop is enabled).
