Note: When you load a setting that uses the “random” option, the saved phase offset
value is recalled. If you want to randomize the phase setting again, choose “new
random” from the Distribution pop-up menu.
• Level knob and field: Determine the amount of effect signal routed back to the input.
• Warmth button: Enable or disable a distortion circuit, suitable for warm
overdrive effects.
• Low/High Cut sliders and fields: Set the cutoff frequency of the lowpass (LP) and
highpass (HP) filters.
• Filter button: Enable or disable the filter section.
• (Out) Mix slider and field: Determine the balance of dry and wet signals. Negative
values result in a phase-inverted mix of the effect and direct (dry) signal.
Ringshifter
Logic Pro Ringshifter overview
Ringshifter combines a ring modulator with a frequency shifter effect in a clear, compact
interface. Both effects were popular during the 1970s and are currently experiencing
a renaissance.
The ring modulator modulates the amplitude of the input signal using either the internal
oscillator or a side chain signal. The frequency spectrum of the resulting effect signal
equals the sum of, and the difference between, the frequency content in the two original
signals. Its sound is often described as metallic or clangorous.
The frequency shifter moves the frequency content of the input signal by a fixed amount
and thereby alters the frequency relationship of the original harmonics. The resulting
sounds range from sweet and spacious phasing effects to robot-like timbres.
Note: Do not confuse frequency shifting with pitch shifting. Pitch shifting transposes the
original signal, leaving its harmonic frequency relationship intact.
