5 - Effects Core Effects Descriptions 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. Feedback In Phase Shifter Out Signal path = Stereo LFO Center LFO Parameter LFO Center Feedback LFO Rate LFO Depth Waveform LFO L/R Phase LFO Rate Description Sets the initial offset of the LFO and changes the position of the peaks and notches. Range: 0% to 100% Increases the depth of the notches and height of the peaks. Range: 0% to 100% Controls the sweep rate of the Low Frequency Oscillator. Range: .01Hz to 10Hz Controls how much the Center Frequency is swept by the LFO. Range: 0% to 100% Selects a Sine or Triangle wave for the LFO Controls the stereo width by adjusting the phase difference between the left and right sweeps. Range: -180° to +180° 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 Speed Description Switches between slow or fast rotor speeds with acceleration and deceleration as the speed changes. 76 Creative Professional
