Chorus [CHO]
5.3
A chorus unit creates one or more delayed copies of the input signal and modulates each of these to create the
layered effect of different voices. Used subtly, the effect can be ambient and liquid, while more extreme settings
can produce a vibrato or “Leslie” effect. The Axe-Fx II offers a high-quality, multi-voice stereo chorus capable of
producing anything from exceptionally smooth ensemble effects to a wildly detuned warble.
Each Axe-Fx II preset can use two fully independent
Chorus
blocks.

Basic Chorus Parameters
TYPE
– This control instantly sets other Chorus parameters for different useful sound settings. Types include:
DIGITAL MONO, DIGITAL STEREO, ANALOG MONO, ANALOG STEREO, JAPAN CE-2, WARM STEREO, 80’S STYLE,
TRIANGLE CHORUS, 8-VOICE STEREO, and DIMENSION. All “ANALOG” types use an algorithm which models the
behavior of classic bucket brigade (BBD) units. VINTAGE TAPE uses a unique algorithm to models the behavior
of a tape delay used as a chorus unit. Rate, Depth, Level, Balance, Bypass Mode, and Global Mix are not
affected when you change TYPE.
NUMBER OF VOICES
– Each stereo channel in the chorus can have from one to four voices. Increasing the
number of voices increases the fullness of the effect. Use two voices for a vintage chorus effect, or use up to
eight for a lush, multi-layered ensemble.
RATE
– This controls the speed at which the chorus oscillates. Use low settings with higher depths for slow-
moving sounds. Increase the rate and depth for vibrato effects. Set fully counterclockwise to sync the chorus
LFO to global LFO1. When
RATE
is shown in parenthesis, it is being set automatically by the
TEMPO
parameter
(see below). Set the
TEMPO
to “NONE” for manual control.
DEPTH
– Sets the delay modulation, which determines the amount of detune heard from each voice.
Tip:
Rate and depth are usually adjusted inversely (high rate/low depth or low rate/high depth), but other settings can also
produce “interesting” effects. For precise control of depth, turn the AUTO DEPTH parameter on the ADVANCED page to OFF.
MIX
– Sets the ratio of wet and dry (duplicated from the MIX page). A setting of 50% produces the most
prominent effect. Try setting the mix to 100% for vibrato effects.
TEMPO
– Sets the chorus rate in rhythmic relation to the global tempo. For example, if the tempo is set to
“1/4” and the global tempo is 120 BPM, the chorus modulation rate will automatically be set to 2 Hz (BPM/60
= Hz). To ignore the global tempo, set the tempo control to NONE.
