Vintage Chorus
This models a chorus best-known for being built into a guitar
amp. You can use the Speed and Depth knobs for an even
broader range of possibilities than on the original device.
Speed [Hz] [0.10…10.00]
This controls the speed of the chorus’ LFO. The default is
0.48 Hz.
Source [List of Dmod Sources]
This selects a modulation source to control the Speed. For a
list of Dmod sources, see the “Dynamic Modulation Source
List” on page 910.
Amount [–10.0…+10.0]
This controls the depth and direction of the Speed
modulation.
Depth [0…100]
Sets the depth of LFO modulation. The default is 58.
Source [List of Dmod Sources]
This selects a modulation source to control the Depth.
Amount [–100…+100]
This controls the depth and direction of the Depth
modulation.
Manual [1…100]
This adjusts the offset of the LFO sweep, effectively
increasing the center delay time of the chorus. The default is
1.
When Depth is set to the maximum of 100, this has no
effect.
OUTPUT
Output Mode [Mono, Stereo]
The chorus can function either in mono or stereo.
Wet/Dry [Dry, 1: 99…99:1, Wet]
Sets the balance between the “wet” processed sound and the
dry input. The default is 50:50.
Source [Off…Tempo]
Selects a modulation source for Wet/Dry.
Amount [–100…+100]
Sets the modulation amount for Wet/Dry.
Black Chorus
Modeled after a classic stereo chorus known for both crystal-
clean tone and quiet operation, and especially well-suited to
tine electric pianos.
Speed [Hz] [0.10…10.00]
This controls the speed of the LFO. The default is 0.8 Hz.
Source [List of Dmod Sources]
This selects a modulation source to control the Speed. For a
list of Dmod sources, see the “Dynamic Modulation Source
List” on page 910.
Amount [–10.0…+10.0]
This controls the depth and direction of the Speed
modulation.
Intensity [1…100]
This controls different things, depending on the Mode
setting. The default is 66.
When Mode is set to Chorus, Intensity blends between the
wet and dry signals.
When Mode is set to Pitch Modulation, Intensity blends
between chorus (at 0) and vibrato (at 100).
When Mode is set to Flanger, Intensity controls the
feedback amount.
Source [List of Dmod Sources]
This selects a modulation source to control the Intensity.
Amount [–100…+100]
This controls the depth and direction of the Intensity
modulation.
Width [0…100]
This controls the amount of LFO modulation. The default is
58.
Source [List of Dmod Sources]
This selects a modulation source to control the Width.
Amount [–100…+100]
This controls the depth and direction of the Width
modulation.
Mode [Chorus, Pitch Modulation, Flanger]
This controls the basic sound of the effect.
Chorus is a standard chorus sound.
Pitch Modulation is a lighter chorus effect.
Flanger adds feedback, for more extreme timbres.
Input Gain [0…100]
This controls the input into the effect. High levels will add
saturation.
OUTPUT
Output Mode [Mono, Stereo]
This controls whether the output is stereo or mono. When set
to Stereo, the left-right spread is controlled by the Width
parameter.
