Effect Guide
812
058: Doppler
This effect simulates the “Doppler effect” of a moving
sound with a changing pitch, like the siren of a passing
ambulance. Mixing the effect sound with the dry
sound will create a unique chorus effect.
DOPPLER
Pitch Depth [0…100]
With the Doppler effect, the pitch is raised as the sound
approaches, and the pitch is lowered as the sound goes
away. This parameter controls the amount of this pitch
variation.
Source [Off…Tempo]
Selects the modulation source of pitch variation.
Amount [+/–100]
Sets the modulation amount of pitch variation.
Pan Depth [+/–100]
This sets the width of the stereo image of the effect
sound. With larger values, the sound seems to come
and go from much further away. With positive values,
the sound moves from left to right; with negative
values, it moves from right to left.
Source [Off…Tempo]
Selects the modulation source of panning.
Amount [+/–100]
Sets the modulation amount of panning.
LFO
Mode [Loop, 1-Shot]
This selects whether the Doppler effect repeats
continuously (
Loop
), or cycles once and then stops (
1-
Shot
).
When
Mode
is set to
Loop
, and
Dmod Sync
is set to
On
, you can reset the LFO via Dmod (as specified by
the
Source
parameter, below).
When
Mode
is set to
1-Shot
, the Doppler effect
happens only once when triggered, and then stops
until it is triggered again. The trigger source is
specified by the
Source
parameter, below. Note that
this requires you to manually trigger the effect;
otherwise, you won’t hear the Doppler at all.
Dmod Sync [Check-box]
When this is
On
, and
Mode
is set to
Loop
, you can
reset the LFO via Dmod (as specified by the
Source
parameter, below).
Source [Off…Tempo]
Selects the LFO reset modulation source.
The effect is triggered when the MIDI value changes
from 63 or smaller to 64 or higher.
Frequency [Hz] [0.02…20.00]
This sets the LFO speed, in Hz. It applies only when
MIDI/Tempo Sync
, below, is
Off
.
Source [Off…Tempo]
This selects a modulation source for the
Frequency
.
Amount [–20.00…+20.00]
This sets the
Frequency
modulation amount, in Hz.
MIDI/Tempo Sync [Check-box]
BPM [MIDI, 40.00…240.00]
Base Note [ … ]
Times [x1…x32]
When
MIDI/Tempo Sync
is on, the LFO speed is set by
BPM
,
Base Note
, and
Times
, instead of
Frequency
. For
more information, see “MIDI/Tempo Sync” on
page 777.
Type [Individual, Common1, Common2]
This controls whether the effect uses its individual
LFO, or one of the Common FX LFOs. For more
information, see “LFO Type” on page 777.
Common LFO Phase Offset [degrees] [+/–180]
When Type is set to
Common FX LFO 1
or
2
, this lets
you offset the phase from the master LFO.
OUTPUT
This is the standard effects output section, with
modulatable control over wet/dry balance. For more
information, see “OUTPUT” on page 764.
