Show Cue System

If I can assinge a key to cue in the next cue but I can aasinge a fade button for scen change music which can't be timed alsostopping a sound cue I have soem back ground sound for soem scenes which I cant autonalicaly cue out when the video switces so when I fade out the scene change music fades out...

Desk top show on project when SCS is not open , when it is it goes to black as pervious version, but when I put video cue onto play on external monitor nothing come sup, just the screen remaining black


I can play in in edit mode on the preview but clicking back on Monitors and it's blank
