Korg NAUTILUS Series

Chorus, Flanger, and Phaser 049: Stereo Random Flanger
807
049: Stereo Random Flanger
The stereo effect uses a step-shape waveform and random
LFO for modulation, creating a unique flanging effect.
FLANGER
Delay Time [msec] [0.0…50.0]
Sets the delay time from the original sound.
Depth [0…100]
Sets the depth of LFO modulation.
Feedback [+/–100]
This controls the intensity of the flanger. For more
information, see “Feedback” on page 806.
High Damp [%] [0…100]
This sets the amount of high-frequency attenuation in the
flanger’s feedback loop. Increasing the value will reduce
high-frequency harmonics.
LFO
These parameters control the shape and speed of the step
LFO. They are identical to those in the Stereo Random
Filter; for more information, see “LFO” on page 781.
OUTPUT
Wet/Dry [–Wet… –1:99, Dry, 1: 99…Wet]
Sets the balance between the “wet” processed sound and the
dry input. Negative values invert the phase of the wet signal.
This interacts with Feedback; for more information, see
“Feedback” on page 806.
Source [Off…Tempo]
Selects a modulation source for Wet/Dry.
Amount [+/–100]
Sets the modulation amount for Wet/Dry.
050: Stereo Envelope Flanger
This Flanger uses a MIDI-triggerable envelope generator for
modulation. This lets you create sequences with flanger
sweeps which always happen on the same beat, for instance.
You can also control the Flanger directly using a modulation
source.
CONTROL
Sweep Mode [EG, Dmod]
When Sweep Mode is set to EG, the envelope generator
controls the flanger. Note that this is the effect’s own EG, and
isn’t related to the Program’s other EGs (Filter, Amp, etc.).
The Source parameter, below, selects the source that starts
the envelope generator. If you select Gate, for example, the
envelope will be triggered by note-ons.
The EG is triggered when the MIDI source’s value
changes from 63 or smaller to 64 or higher.
When Sweep Mode is set to Dmod, the modulation source
directly controls the flanger. Select the modulation source
using the Source parameter, below.
Source [Off…Tempo]
Selects the modulation source that triggers the EG (when
Sweep Mode = EG), or the modulation source that causes
the flanger to sweep (when Sweep Mode = Dmod).
EG
Attack [1…100]
Sets the EG attack time. For more information Attack and
Release, see the graphic under “Attack [msec]” on page 764.
Decay [1…100]
Sets the EG decay time.
FLANGER
L Delay Bottom [msec] [0.0…50.0]
Sets the lower limit of the left-channel delay time. For more
information on the Bottom and Top settings, see the graphic
under “Frequency Bottom” on page 779.
L Delay Top [msec] [0.0…50.0]
Sets the upper limit of the left-channel delay time.
R Delay Bottom [msec] [0.0…50.0]
Sets the lower limit of the right-channel delay time.
R Delay Top [msec] [0.0…50.0]
Sets the upper limit of the right-channel delay time.
