I put your audio example in a DAW and so far I can see besides the 3/16 (1/8dot) they add a 8/16 (1/2).
Did the edge really use it like that?
However, with the dual delay I don't see any way to adjust the volume to a lower level of the second delay (8/16).
That's why I am using now two single dealys. Sounds good to me too, but different.
