by the amount of wet signal re-injected into the feedback loop as shown in Figure 32. Increasing
the feedback enhances frequency components least affected by the delay line and located at even
harmonic intervals of the fundamental frequency. As the feedback is increased, these peaks become
sharper resulting in an apparent change in the pitch of the signal.

Tuning
The delay length, in milliseconds, is adjusted with the Delay knob. The length of this delay can be
modulated by a certain amount depending on the adjustment of the Depth knob. In the left position,
there is no modulation and the length of the delay line remains constant. As the knob is turned to
the right, the length of the delay line starts to oscillate by an amount which increases as the knob is
turned clockwise and at a frequency fixed with the Rate knob. The Feedback knob is a gain knob
used to fix the ratio of wet signal re-injected into the delay. Finally, the Mix knob determines the
amount of dry and wet signal in the output signal from the module. When this knob is adjusted in
its leftmost position, only dry signal is sent to the output, in its center position, there is an equal
amount of dry and wet signal in the output signal while in its rightmost position, only wet signal is
