In all cases there is a player. Cue is only a container. When you start cue, BEYOND create a player for this Cue. Player take care about the time. Time is common for all types of content - laser, beams, dmx, object sequencer. So, what you need is player control, I mean a Live Control, Animation speed. Take a look at Object Tree, it show all published properties. The Live Control object embedded into all 4 main live elements - cue, master, zone, protrack. if you play the DMX cue in the grid (trackless tracks mode), then it might be a question to address it. That is why there are ProTracks, the player that can be easily addressed from the script, externally and so on.
