EFFECT TYPES: CHORUS
+VARIATION Button
Two phase settings are available for the Tri-Chorus.
One option produces a more traditional Chorus sound
where the phases of the three Choruses are tilted by
90, 180 and 270 degrees respectively. The other option
is an asymmetric type where the phase and depth
parameters are tuned to produce a wilder and more
“uncontrolled” Chorus effect.
Flanger
Introduction
The Flanger belongs to the same “family” of
modulation effects as the Chorus effect. The signal is
split, and one of the signals is pitch modulated.
The characteristic “flanging” sound occurs when the
pitch-modulated part of the signal is slightly delayed
and fed back to the input of the effect algorithm. In a
Flanger effect, the delay times of the modulated signal
are typically shorter compared to a Chorus effect.
Experiment with the Feedback parameter to get an
idea of the effects you can achieve.
Normal or TZF (Through Zero Flange) mode
Two Flanger modes are available. To select the Flanger,
press the EFFECT button repeatedly. The LED will turn
red, indicating Normal mode. Press the EFFECT button
once more, and the LED will turn green, indicating TZF
mode. The TZF mode emulates the original way of
creating a flange effect, with two identical pieces of
audio material being played back simultaneously on
two tape decks and then being mixed on a third deck.
The flanging effect was achieved by slowing down and
speeding up the two decks at different times. An
essential part of the special effect created this way is
the unique phase cancellation occurring when the two
signals pass each other in time (the zero point). A
conventional Flanger pedal/ algorithm tries to emulate
this effect, but because the two signals will never cross
each other in time, until now, phase cancellation wasn’t
possible.
But with the NOVA Modulator’s TZF mode, it is.
DEPTH Knob
Use the DEPTH knob to set the intensity of the effect.
The more you turn the knob clock-wise, the more “out of
tune” the modulated part of the signal is.
