Each delay type has a common set of controls for setting up the delay (Delay
Level, Time, and Repeats). There are also two custom controls (Modify 1, Modify
2) that offer added flexibility by controlling specific settings for each delay type.
The table below shows what each these knobs control with each delay type.
0.5 - 8 Seconds
Reverse
Modulated
Analog
Slapback
LoFi
Tape
Pong
The 0.5–8 second (Digital), Modulated, Reverse, and Pong delay types have a
repeat hold function when the Repeats knob is turned fully clockwise. This
means the input of the delay is shut off and the delay will repeat indefinitely
until the Repeats knob is moved off the maximum position.
Analog, Slap, LoFi, and Tape delays have an "analog" behavior (pitch shifting
sound) when the Time is changed. When the Repeats knob is set to the
maximum setting, these delays can become unstable just like the actual delays
they were modeled from do.
The Modulation parameter adds chorusing or a vibrato effect to the delay.
The first half of the knob range is chorusing with increasing depth. The
second half of the knob range is vibrato with increasing depth.
