Korg NAUTILUS Series

Chorus, Flanger, and Phaser 045: Bi Chorus
803
Status 1…6 [Always On, Always Off,
On
→Off (Dmod), Off→On (Dmod)]
This turns the tap on or off, or allows its output level to be
modulated by the selected Dmod source.
Always On: Output is always on. (No modulation)
Always Off: Output is always off. (No modulation)
On→Off (Dmod): Output level fades from on to off via the
modulation source.
Off→On (Dmod): Output level fades from off to on via the
modulation source.
Combining these parameters, you can change from 4-phase
chorus to two-tap delay by crossfading them gradually via
the modulation source during a performance.
Tap 1 Feedback
Tap1 Feedback [+/–100]
Sets the amount of feedback from Tap1.
Source [Off…Tempo]
This selects a modulation source to modulate the tap output
levels (as set by Status, above) and the Tap 1 Feedback
amount.
Amount [+/–100]
Sets the modulation amount for the Tap 1 Feedback.
Panning Preset [1: L 1 2 3 4 5 6 R, 2: L 135 246 R,
3: L 1 3 5 2 4 6 R, 4: L 1 4 5 6 3 2 R]
This selects combinations of stereo panning patterns for the
tap outputs.
LFO
Frequency [Hz] [0.02…13.00]
This sets the LFO speed, in Hz.
OUTPUT
This is the standard effects output section, with modulatable
control over wet/dry balance. For more information, see
“OUTPUT” on page 762.
045: Bi Chorus
This effect lets you place two independent chorus/flanger
units in series or in parallel. If placed in series, feedback can
be applied to the sound that has passed through the two
chorus modules, creating even more complex modulation.
CHORUS1
Manual [0…100]
Sets the delay time for chorus 1.
LFO1 Depth [0…100]
Sets the LFO modulation depth for chorus 1.
Source [Off…Tempo]
Selects the modulation source that will control LFO
modulation depth.
Amount [+/–100]
Sets the amount by which the chorus 1 LFO modulation
depth will be controlled.
Feedback [0…100]
Sets the feedback amount for chorus 1.
CHORUS2
Manual [0…100]
Sets the delay time for chorus 2.
LFO2 Depth [0…100]
Sets the LFO modulation depth for chorus 2.
Amount [+/–100]
Sets the amount by which the chorus 2 LFO modulation
depth will be controlled.
Feedback [0…100]
Sets the feedback amount for chorus 2. When Routing is set
to Serial, this feeds back into Chorus 1, and Chorus 1’s own
Feedback setting is ignored.
LFO1/2
LFO1/2 Lock [Unlock, Lock-LFO1,
Lock-Common1, Lock-Common2]
This selects the LFO(s) used by the two choruses.
Unlock: LFO 1 and LFO 2 will operate independently.
Lock-LFO 1: both choruses will use LFO 1, with an
optional phase offset for LFO 2 (see “LFO2 Phase
[degrees],” below).
Lock-Common 1 or Lock Common 2: both choruses will
use the selected FX Common LFO, with an optional phase
offset for LFO 2.
