Phase Shifter
A phase shifter produces a fixed number of peaks and notches in the audio spectrum
which can be swept up and down in frequency with a low frequency oscillator (LFO).
This creates a swirly, ethereal sound with harmonically rich sound sources of a type of
pitch shift with simpler sounds. The phase shifter was invented in the 1970’s and the
characteristic sound of this device evokes emotions of that musical era.
By setting the LFO Depth to zero and tuning the LFO Center, a fixed multi-notch filter is
created.
Rotary
This is a simulation of a rotating speaker used on organs. The rotating speaker was
invented to give static organ tones a pipe organ type of animation, but this distinctive
sound became a legend in its own right. Spinning a sound around the room creates a
doppler pitch shift along with many other complex and musically pleasing sonic effects.
The Rotary incorporates acceleration and deceleration as you switch between the two
speeds.
Parameter
Description
LFO Center
Sets the initial offset of the LFO and changes the position of the
peaks and notches. Range: 0% to 100%
Feedback
Increases the depth of the notches and height of the peaks.
Range: 0% to 100%
LFO Rate
Controls the sweep rate of the Low Frequency Oscillator.
Range: .01Hz to 10Hz
LFO Depth
Controls how much the Center Frequency is swept by the LFO.
Range: 0% to 100%
Waveform
Selects a Sine or Triangle wave for the LFO
LFO L/R Phase
Controls the stereo width by adjusting the phase difference
between the left and right sweeps. Range: -180° to +180°
Parameter
Description
Speed
Switches between slow or fast rotor speeds with
acceleration and deceleration as the speed changes.
