The MISC category provides primarily modulated and pitch-varying effects.
Chorus
Chorus creates a lush, full sound by combining two or more signals together where one is unaffected and the other
signals vary in pitch very slightly over time. Chorus is commonly used to fatten up tracks and to add body to guitars
without colouring the original tone. Chorus can also be used with discretion to thicken a vocal track.
Flanger
This effect was originally created by simultaneously recording and playing back two identical programs on two tape re-
corders, then using hand pressure against the flange of the tape reels to slow down first one machine, then the other.
Phaser
The Phaser automatically moves frequency notches up and down the spectrum of the signal by means of a low fre -
quency oscillator (LFO), creating an oscillating “comb filter” type effect. This effect is very useful on keyboards (espe -
cially pad presets) and guitars.
Tremolo
Tremolo/Pan creates rhythmic changes in signal amplitude. Tremolo is obtained by setting Phase to 0 degrees, and
affects both channels’ amplitude simultaneously. If the Phase is set to 180 degrees, an AutoPanner effect is generat-
ed, with the amplitude of one channel being raised whilst that of the other channel is lowered.
Vibrato
Vibrato is obtained by smoothly varying the pitch of the signal just sharp and flat of the original at a determined rate.
Phase controls whether the pitch of both channels is modulated together, or in an opposite direction.
Rotary
Rotary speaker cabinets were designed to provide a majestic vibrato/choir effect for electronic theatre and church
organs. The most well known rotary speaker is the Leslie™ Model 122, which has two counter-rotating elements: a
high-frequency horn and a low-frequency rotor with slow and fast speeds.
Pitch Shift
This effect shifts the frequency spectrum of the input signal. Altering the pitch of a sound produces a wide range
effects - from subtle detunes to full interval shifts up or down a two octave range. The Pitch Shift effect is a chromat-
ic shifter, meaning all notes of the scale are shifted by the same interval. Pitch Shift is very useful with guitar tracks,
monophonic synth lines, or where special vocal effects are needed.
Detune
Detune adds a slightly pitch-shifted version of the original source, thickening the sound. This creates a particularly
effective simulation of “double-tracking.” Also a great alternative to the Chorus effect, adding the richness of a chorus
without the audible sweep caused by the chorus rate.
