Delay Time Fine
Makes fine adjustments (in units of 1 ms) to the delay time.
Tap Time
(Used Only with Pan)
Adjusts the delay time of the right channel delay. This setting
adjusts the right channel delay time relative to the left
channel delay time, which is referenced as 100%.
Feedback
"Feedback" refers to the return of a delay signal back to the
input. This parameter adjusts the amount of signal returned.
Higher values increase the number of the delay repeats.
High Cut
The high-cut cuts the frequency component above the set
frequency. This parameter adjusts the frequency where the
high-cut starts working. When set to "Flat," the high-cut does
not affect the sound.
Delay Level
