The FLANGER function is available only in configurations displaying "FLAN" in the
configuration title.
Flanging involves splitting the input signal into at least two individual delayed signals
(Voice 1 and Voice 2) , then modulating these delayed signals so that, when summed
back with the direct signal, phase cancellations will occur at some frequencies while
peaks in the response will occur at others.
The PARAMETER SELECT control will allow you to access these FLANGER parameters:
FLANGER I/O The FLANGER I/O parameter determines whether the Flanger is active
or bypassed for the current preset.
LEVEL 1 The LEVEL 1 parameter determines the volume of Voice 1 relative to
Voice 2.
Tip: Keep the settings of these levels high and use the DIR/EFF mix
parameter in the Mixer function to control the overall amount of flanged
signal.
PAN 1 The PAN 1 parameter allows you to pan Voice 1 to the left or right
channel.
DEPTH 1 The DEPTH 1 parameter adjusts the amount of modulation of Voice 1.
Lower DEPTH settings produce more subtle effects, while higher
settings will result in a more drastic effect.
RATE 1 The RATE 1 parameter determines the speed at which Voice 1 is
modulated.
LEVEL 2 The LEVEL 2 parameter determines the volume of Voice 2 relative to
Voice 1.
PAN 2 The PAN 2 parameter allows you to pan Voice 2 to the left or right
channel.
DEPTH 2 The DEPTH 2 parameter adjusts the amount of modulation of Voice 2.
Lower DEPTH settings produce more subtle effects, while higher
settings will result in a more drastic effect.
RATE 2 The RATE 2 parameter determines the speed at which Voice 2 is
modulated.
REGEN The REGENERATION parameter determines how much of the the
delayed output signal is fed back into the input. More regeneration
produces a more pronounced "jet airplane" type of effect.
