Set the Logic Pro Ringshifter mode
The four mode buttons determine whether the Ringshifter operates as a frequency shifter
or as a ring modulator.
Ringshifter mode parameters
• Single Freq Shift button: Turn on to generate a single, shifted effect signal.
The oscillator Frequency control determines whether the signal is shifted to a positive
value on the right side of the Frequency knob or to a negative value on the left side.
• Dual Freq Shift button: Turn on to produce one shifted effect signal for each stereo
channel—one is shifted up, the other is shifted down.
The oscillator Frequency control determines the shift direction towards the left or the
right channel.
• OSC Ring Mod button: Enable to use the internal sine wave oscillator to modulate the
input signal.
• Side Chain Ring Mod button: Enable to modulate the amplitude of the input signal with
the audio signal assigned via the side chain input. See Work in the plug-in window in
Logic Pro.
The sine wave oscillator is switched off, and the Frequency controls are disabled when
Side Chain mode is active.
Logic Pro Ringshifter oscillator parameters
In both frequency shifter modes and ring modulator OSC mode, the internal sine wave
oscillator is used to modulate the amplitude of the input signal.
• In the frequency shifter modes, the Frequency parameter controls the amount of
frequency shifting, either up or down, applied to the input signal.
• In the ring modulator OSC mode, the Frequency parameter controls the frequency
content, or timbre, of the resulting effect. This timbre can range from subtle tremolo
effects to clangorous metallic sounds.
