102 Chapter 8 Modulation
Modes
The four Mode buttons determine whether the plug-in either operates as a frequency
shifter or as a ring modulator. The frequency shifter offers the Single and Dual settings.
The ring modulator provides the OSC and Side Chain settings.
• Single (Frequency Shifter): The frequency shifter generates a single shifted effect
signal. The position of the large Frequency rotary control determines whether the
signal is shifted up (positive value) or down (negative value).
• Dual (Frequency Shifter): The frequency shifting process produces one shifted effect
signal for each stereo channel—one is shifted up, the other is shifted down. The
position of the large Frequency rotary control (in relation to the 0 point) determines
the shift direction in the left versus the right channel.
• OSC (Ring Modulator): The Ring Modulator uses the internal sine wave oscillator to
modulate the input signal.
• Side Chain (Ring Modulator): The Ring Modulator modulates the amplitude of the
input signal with the audio signal assigned via the side chain of the plug-in.
Note: The internal sine wave oscillator has no effect in the Side Chain mode, and for
this reason, the oscillator frequency controls are not accessible.
The Oscillator
In both the Ring Modulator OSC mode and the Frequency Shifter modes, the internal
sine wave oscillator serves as an amplitude modulator of the input signal. The large
Frequency rotary control is used to set the frequency of the sine oscillator. It can be set
between 0 and ±5,000 Hz in extremely fine increments.
• In the Frequency Shifter modes, this parameter controls the amount of frequency
shifting (up and/or down) applied to the input signal.
• In the OSC mode of the ring modulator, this parameter controls the frequency
content (timbre) of the resulting effect. This timbre can range from subtle tremolo
effects to clangorous metallic sounds.
To optimize adjustment, the scaling of the Frequency rotary control can be switched via
the Lin(ear) and Exp(onential) buttons. The exponential scaling offers extremely small
increments around the 0 point, which is useful for programming slow moving phasing
and tremolo effects. In the Lin(ear) mode, the resolution of the scale is even over the
entire control range.
Further to these options, the oscillator frequency can be modulated with an envelope
follower and LFO (see later). The oscillator is capable of frequency sweeps through the
0 Hz point. The modulation depth for the envelope follower and LFO is set indepen-
dently, by using the corresponding bipolar slider.
