How to trigger a specific outro array based on currently playing audio from random array?

No problem! I didn’t expect to find the solution on my own, let alone that quickly, so I’m glad I could help you in the process!

And just to answer that last question, I created the cue points in Reaper, by setting markers in DAW and then rendering the files with the markers baked in (which gives you the cue point(s)). But you probably saw that in the video :sweat_smile:.
