•
Ldr Peak
: Ladder peak filter that boosts frequency content at the cutoff frequency. The amount
of boost can be set using
Reso
.
•
Ldr Notch
: Ladder notch filter that attenuates frequency content in two narrow bands above
and below the cutoff frequency.
•
SV Notch
: 4-pole state-variable notch filter that attenuates or boosts frequency content at the
cutoff frequency. The amount of attenuation or boost can be set using
Reso
.
•
SV BR
: State-variable band reject filter that attenuates frequency content in a narrow band
slightly below cutoff frequency.
The following controls are available in this mode:
The following controls are available per filter:
Cutoff
(adjusts the frequency below which signals
will be attenuated);
Reso
(with a value greater than 0, this control will boost a small frequency
range around the cutoff frequency); and
Gain
(controls the amplitude increase after the filter,
which can be used to compensate for amplitude reduction due to the filter, or to increase the soft
saturation of the effect — this one is only available for
Ldr Peak
and
Ldr Notch
).
•
Cutoff
: Adjusts the cutoff frequency.
•
Reso
: Adjusts the resonance amount of the filter. Turning the control to the right makes the
frequency content at the cutoff frequency more pronounced.
•
Gain
: Adjusts the output level of the filter. Setting Gain to high values can be used to apply a
soft saturation effect. This control is not available when selecting the
Ldr
filter types.
15.5.7. Effect
Effect mode is a collection of special filters that transform the frequency spectrum in specific
ways. It offers four different filter types that change the character of the filter.
You can select the filter type using the Type selector:
•
Frm 1
: Variation 1 of a formant filter that produces resonances typical to those of the human
voice.
•
Frm 2
: Variation 2 of a formant filter that produces resonances typical to those of the human
voice.
•
Vow A
: Variation A of a special filter that mimics the way vowel sounds are produced by the
human mouth, similar to classic talk box effects.
•
Vow B
: Variation B of a special filter that mimics the way vowel sounds are produced by the
human mouth, similar to classic talk box effects.
•
Phaser
: Classic phaser effect that produces a number of peaks and troughs in the frequency
spectrum.
The following controls are available in this mode when the
Vow
or
Phaser
filter types are selected:
•
Cutoff
: Adjusts the filter frequency, effectively shifting the position of the effect in the
frequency spectrum.
•
Reso
: Adjusts the resonance amount. Turning the control to the right makes the effect more
pronounced.
The following controls are available in this mode when the
Frm
filter types are selected:
•
Talk
: Adjusts the the frequency response of the filter in order to produce different vowel
sounds.
