Modulation and Pitch Shift
055: Stereo Vibrato
This effect modulates the pitch of the input signal to
create a shimmering timbre. AutoFade allows you to
increase or decrease the shimmering speed.
AUTOFADE
Autofade lets you modulate the LFO Frequency via a
simple envelope, triggered by a Dmod source. This is
enabled by setting LFO Frequency Mod to
AUTOFADE, and can only be used when BPM/Tempo
Sync is Off.
The intensity of the autofade’s effect is controlled by
the normal Amount parameter, under Frequency.
Autofade example
The diagram below shows a setup with note-ons
triggering the autofade, causing the LFO to speed up
from 1.0Hz to 4.0Hz.
The AUTOFADE Source is set to Gate1, LFO
Frequency Mod is set to AUTOFADE, LFO Frequency
[Hz] is set to 1.0, and the modulation Amount is set to
3.0.
Source [Off…Tempo]
Selects the trigger source for the Autofade.
AutoFade is triggered when the Dmod value changes
from 63 or smaller to 64 or higher, and turns off again
when the Dmod value goes below 64.
Rate [1…100]
Sets the speed of the fade-in. Higher values are faster.
Fade-In Delay [msec] [00…2000]
This sets the time from the trigger source turning on
(going above a value of 63) until the fade-in starts.
LFO Frequency Mod [Dmod, AUTOFADE]
This selects whether the LFO will be modulated by the
normal Frequency Dmod source, or by the Autofade
envelope.
VIBRATO
Depth [0…100]
Sets the depth of LFO modulation
Source [Off…Tempo]
Selects the modulation source of the LFO modulation
depth.
Amount [+/–100]
Sets the modulation amount of the LFO modulation
depth.
LFO
Waveform [Triangle, Sine]
Selects the LFO Waveform.
Shape [+/–100]
Changes the curvature of the LFO Waveform. p.780.
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.
