Feedback

Controls the number of delay repeats by feeding the delay output signal back into the delay input. This
creates a series of delay repeats, each slightly attenuated until they become inaudible. Higher settings create
more repeats; lower settings reduce the number of repeats. When this knob is turned fully clockwise, it
engages Repeat Hold – delay repeats play back in an infinite loop, but no further input signal is introduced
into the delay effect. Repeat Hold is available only on Studio, Digital and Pong Delay.

Ducker Threshold

Studio and Digital delays offer a “ducking” feature, which causes the delay repeats to attenuate (or get softer)
by -6dB when live (or input) signal is present. This allows the delay to remain as an effect, and not clash with
the original signal. The higher this value is set, the louder an input signal must be for the ducking to take
place.

Smear

This parameter controls the amount of “smear,” or signal degradation and frequency loss. Particularly evident
in the Tape Delay, the higher the setting, the more each delay repeat loses intelligibility compared to the
original signal.

Tap Ratio

Tap Ratio sets the length between the first and second tap repeats of the Pong Delay. With this control set at
12 o’clock, repeats are evenly alternated between left and right channels. As this knob is turned counter-
clockwise, the first tap occurs earlier and the second tap occurs later than they did at the 12 o’clock position.
When the knob is turned clockwise, the first tap occurs later and the second tap occurs earlier.

Depth

This controls the intensity of modulation, or “depth” in the Modulated Delay. Lower settings produce a more
subtle effect, while higher values give a more “seasick” feeling.

Tempo Button

Tapping this button twice sets the delay times. The Tempo button LED flashes the tempo tapped in, and delay
taps will be synchronized to the flashing LED. Use the Time Range knob to increase or decrease delay times
after tapping in a tempo.

Note

: When Delay Feedback is at maximum (fully clockwise) in some programs the mode changes to hold the

audio in a constant loop.  This is indicated in the Effects Data Chart as “+H”.

MODULATED EFFECTS

Chorus

Chorus creates a lush, full sound by combining two or more signals together where one is unaffected and the
other signals vary in pitch very slightly over time. Chorus is commonly used to fatten up tracks and to add
body to guitars without coloring the original tone. Chorus can also be used with discretion to thicken a vocal
track.

Knob 1: Speed

 Controls the modulation rate of the Chorus effect. Lower settings are subtle, while higher

values are much more pronounced.

Knob 2: Depth 

Controls the amount of pitch shifting for each voice. Lower settings provide subtle thickening

and warmth to a track, while higher settings give a more pronounced, multi-voice effect.

Knob 3: Voices

 Controls the number of additional Chorus voices. Up to 8 voices can be added, continuously

variable in 100 individual steps.
