5.4 The Effects View 63
Turning this knob clockwise increases the excursion of the center frequency. Note that the
Depth
parameter is also adjustable from the
Play
view.
The Rate knob controls the frequency or rate of the modulation of the center frequency of the
filter. In the case of the Wah Wah effect, turning this knob clockwise increases the rate of the
modulation. In the case of the Auto Wah filter, this knob is labeled Speed and controls the time
constant of the envelope follower. Turning this knob clockwise decreases the time constant, or in
other words the reaction time, of the envelope follower.
The Mix knob allows one to mix the dry and wet signals. In its leftmost position, there is no
output signal from the chorus and one only ears the dry input signals. In its rightmost position, one
only ears the wet signal from the chorus module. In its center position, there is an equal amount of
dry and wet signal in the output signal from the module. Finally, the
Output know is used to adjust
the output level of this module.
5.4.9 Notch Filter
The
Notch Filter
does essentially the opposite of a band-pass filter. It attenuates the frequencies
in a band located around the center frequency and leaves those outside of this band unchanged as
shown in Figure 40. As was the case for the
Wah Wah effect, the filter can be modulated.
The Freq knobs is used to control the central frequency of the filter. Turning this knob clock-
wise increases the center frequency. The Depth knob controls the excursion of the center frequency
of the filter around its center frequency. Turning this knob clockwise increases the excursion of the
center frequency. Finally, the
Rate knob controls the frequency or rate of the modulation of the
center frequency of the filter. Turning this knob clockwise increases the rate of the modulation.
Note that the
Depth
parameter is also adjustable from the Play view.
The Mix knob allows one to mix the dry and wet signals. In its leftmost position, there is no
output signal from the chorus and one only ears the dry input signals. In its rightmost position, one
only ears the wet signal from the chorus module. In its center position, there is an equal amount of
dry and wet signal in the output signal from the module. Finally, the
Output know is used to adjust
the output level of this module.
5.4.10 Guitar Amplifier
The Guitar Amplifier module is a versatile 2-channel amplifier with speaker cabinet and spring
reverb. With relatively few parameters, this amplifier module allows one to obtain a rich variety of
sounds for different music styles.
