Can’t go in to Cue.
You can go it to In, set one of your tracks as a ‘thru’, select which input via the first scene and use the last two scenes on that track to apply effects. You can have a ‘neighbor’ on the track below it for two more. And two more on a master track if you’re not going to use the OT for anything else.
Hold down Cue and turn the level knob to set the Cue output level for the neighbor track if you go that route, or the ‘thru’ track if you did not.
You can also switch the OT to ‘studio’ mode which makes the Cue outs look more like mains. Funtion + Mixer, Control, Audio.
