OFF / ON
• These buttons disable and enable the chorus effect. When the chorus effect is off,
the incoming signal is passed through unaffected.
FEEDBACK
• Range is -50% to +50%. This control regulates the amount of chorus output sig-
nal that is fed back to the input of the delay lines. Negative values apply increas-
ing levels of phase inverted signal to the input.
LFO FREQ
• Range is 0 Hz to 12.7 Hz. Sets the rate of the LFO that is used by both delay lines
to apply vibrato (pitch modulation) to their respective signals.
DRY LEVEL
• Range is 0 % to 100%. Controls the volume of the unchorused signal.
SELECT 1 / 2
• These buttons select a delay line for editing. Unlike the OSC FILTER SELECT
and NOISE FILTER SELECT buttons, the CHORUS SELECT buttons do not
change any modes other than the display.
DELAY 1
• Range is 0 to 127 milliseconds. This control sets the time length of the first delay
line.
MOD 1
• Range is -50 % to +50%. Controls the pitch modulation (vibrato) depth applied
to the first delay line. Negative values apply increasing amounts of phase
inverted LFO modulation. Try setting MOD 1 to a positive value while setting
MOD 2 to a negative value for maximum effect.
WET 1
• Range is -50 % to +50%. Controls the output volume of the first delay line.
Negative values apply increasing levels of phase inverted signal to the output.
DELAY 2
• Range is 0 to 127 milliseconds. This control sets the time length of the second
delay line.
MOD 2
• Range is -50 % to +50%. Controls the pitch modulation (vibrato) depth applied
to the first delay line. Negative values apply increasing amounts of phase
inverted LFO modulation. Try setting MOD 1 to a positive value while setting
MOD 2 to a negative value for maximum effect.
WET 2
• Range is -50 % to +50%. Controls the output volume of the second delay line.
Negative values apply increasing levels of phase inverted signal to the output.
