EQ - FLANGER - DOL
00
- EQ-Flanger-DDL combines
an
EQ
with
a flanger
and
a digital delay. Use flanging to
get
that
"jet aircraft woosh" effect.
EQ - Flanger - DOL Signal Routing
Main
Outputs
The
signal
enters
an
input
level
trim
(parameter 20) followed
by
a
programmable
EQ
and
then
is
routed
to
the flanger. The flanger is routed directly to the output. The left
channel
signal
passes
through
the delay
and
is
routed
back into the flanger.
Another
signal from the
delay
is
routed
to
the
output
on
the right side.
One
feedback
parameter
(12)
controls
both
delay
levels. There
are
two
discrete echoes
that
are
sent
to the left
and
right
outputs
respectively. The signal
from
both
echoes
has
one
level control (parameter 15). There is also
an
external
dry
signal (not
shown)
that
goes
directly from the
input
to
the
output
and
is controlled
with
the mix
parameter
(01).
The
parameters
available for this algorithm are:
01-Mix
02-Volume
See
the
descriptions
under
the Mix
and
Volume Parameters,
in
the
beginning
of this section.
We
recommend
a Mix setting of
99.
03 - Flanger LFO Rate
Range:
00
to 99
This
parameter
controls the rate of modulation
of
the
flanger effect.
04 - Flanger LFO Width
Range:
00
to 99
This
parameter
controls the
range
of the
high
to
low
frequency
sweep
in
the flanger effect.
05 - Flanger Center
Range: 00 to 99
This
parameter
controls the sweep center of the flanger effect. The
larger
the
flanger center, the
wider
will
be
the available width.
06 - Flanger Feedback
Range: -99 to +99
This
parameter
controls the
amount
of feedback
applied
from the
output
to the flanger
input.
The
sign
of the value determines the polarity of
the
feedback.
07 - Flanger Notch Depth
Range: -99 to +99
Controls the
depth
of the notches created
by
the flanging effect. A setting of
00
will disable
the
flanging effect,
and
also provide a doppler effect for
wide
moderately
slow
LFO rates.
