Definitely LDLy, as far as my old eyes can make out!
The plot thickens even more
Linked Delay?? Linked Dual Delay ????
In any case, the Delay effect is greyed out (inactive), and does not appear to be temporarily activated when we hear the swells. In other words, I don't hear delay(s) contributing to the sound during the expressive swells...which I guess argues against the delay being somehow "linked" to the expression control.
