Chapter 7: Editing Effects
Stereo Flange. In the case of the Stereo Flange, the signal is split into three parts
with a dry signal and a separate Delay section for both left and right channels with
one channel flanging up while the other channel flanges down. Once again, this
causes the effect to become more pronounced and dramatic.
DRY
SIGNAL
Pitch Detune. As the name implies, Pitch Detune takes a part of the signal and
detunes it either sharp or flat. When mixed back with the original dry signal, the
popular "12 string guitar" effect is produced.
DRY
SIGNAL
Resonator. This can be thought of as a highly resonant filter, or a filter that is tuned
to a specific frequency with a lot of emphasis, which will cause the frequency that the
resonator is set at to be highly accentuated.
Delay Input
Quad Knob [2] can adjust the level of the signal coming from the Delay output going
into the Pitch Input. The Delay Input parameter is only available when editing a
effects bus which has the Delay effect ahead of the Pitch effect in the selected
Configuration ( Example: Configuration #2, effect send 1).
