Chorus
This effect was originally designed to simulate the sound of
many people singing together (hence the name Chorus) in con-
trast to a single voice. Instrumentally, consider the sound of a
12 string guitar compared to a 6 string guitar.
Chorus is an effect produced by mixing a continuously delayed
version of the audio signal back with the original. The timing of
the delayed version is very small and is controlled by the cho-
rus’s own internal LFO. The characteristic swirling Chorus effect
is the result.
Adding a Chorus effect to a sound
Ensure the function switch is set to SHIFT. Press KEY 3 and
the display will show c L with an alternating value. Turn the
PORTA/DATA knob clockwise. A Chorus effect will be heard.
The Chorus menu table below lists the parameters that may be
edited in for the Chorus processor.
Types of Chorus
Chorus
Chorus provides a stereo effect with a smooth swirling sensa-
tion that fattens up sounds and provides a stereo image.
Chorus retains the definition of the effected sound making it
more suitable for basses, organs and percussive sounds.
Phaser
Although referred to as a Chorus type, the Phaser effect is in
fact entirely different. A portion of the audio signal is split off
and phase shifted at certain frequencies. It is then mixed back
with the original signal to generate the characteristic swishing
effect.
Changing the Type of Chorus
Ensure the function switch is set to SHIFT. Repeatedly press
KEY 3 until the display shows c t alternating with either C h -
Chorus or P h - Phaser. Turn the PORTA/DATA knob to switch
between Chorus and Phaser.
Chorus Speed
Controls how fast the internal LFO is oscillating. A fairly slow
speed is recommended. Higher speeds tend to introduce a
vibrato like quality to the sound.
