Signal flow guide

Has anyone found/made an annotated picture of the signal flow you can access on the OP-1 by pressing shift + mixer? I’m particularly curious about the red exclamation mark that sometimes appears and the number next to it, which always seems to show a 2 or a 4. I’ve tried playing with the track levels/panning/drive + release/highs mids lows but can’t figure out what causes these things to change in the signal flow screen.

This dawg makes a good point.
