54 Chapter 8 Modulation
Set the basic delay time with the Flanger-Chorus knob. Set to the far left position, the
Modulation Delay puts on its flanger cap. As you move towards the center position, it
thinks it’s a chorus. As you move the knob closer to the far right position, you will hear
clearly audible delay taps. This latter type of setting is generally used without
modulation (Width = 0), for doubling effects.
The Stereo Phase knob defines the phase of the modulation between the left and right
stereo sides. At 0°, the extreme values of the modulation are achieved simultaneously
on both sides, at 180°, the extreme values opposite each other are reached
simultaneously.
The Feedback slider determines the intensity at which the effect’s signal feedback is
routed to the input. If you’re going for radical flanging effects, enter a high Feedback
value. If simple doubling is what you’re after, you won’t want any feedback at all. The
Mix slider determines the balance between dry and wet signals.
The 001/011 button offers six further parameters:
If you set True Analog to on, an additional all-pass filter is switched into the signal path.
An all-pass filter shifts a signal’s phase angle, influencing its stereo image. Use Analog
Left and Analog Right to control the way that the allpass filter affects each of the stereo
channels.
The Speed LFO 1 R and Speed LFO 2 R sliders allow independent modulation rate settings
for LFO1 and 2 (for the right stereo channel). These parameters only work if the Free
option is chosen in the Stereo pull-down menu. With Stereo set to Link, the modulation
rates of the left and right stereo channels are tied to each other, and rates are set by
the LFO controls in the Plug-in window. In this situation, the Speed LFO 1 R and Speed
LFO 2 R parameters are non-functional.
Chorus
The Chorus effect is based on a delay line. It’s output is mixed with the original, dry
signal. While the chorus effects delay time is set internally, you can define its
modulation width (Intensity parameter) and modulation frequency (Speed parameter).
The Mix slider determines the balance of dry and wet signals.
