064: Stereo Tremolo
This effect combines a stereo phaser and tremolo, with
linked LFOs. Swelling phaser modulation and tremolo
effects synchronize with each other, creating a soothing
modulation effect particularly suitable for electric piano.
PHASER
Manual [0…100]
Sets the phaser frequency range.
Depth [0…100]
Sets the phaser modulation depth.
Source [Off…Tempo]
Selects the modulation source for the phaser modulation
depth.
Amount [+/–100]
Sets the modulation amount for the phaser modulation depth.
Resonance [+/–100]
Sets the phaser resonance amount.
Wet/Dry [–Wet, –2:98…Dry…2:98, Wet]
Sets the balance between the phaser effect and the dry sound,
feeding into the tremolo. Values are in steps of two (2:98,
4:96 etc). Note that the OUTPUT section’s
Wet/Dry
parameter controls the overall wet/dry balance.
TREMOLO
Shape [+/–100]
Sets the degree of the tremolo LFO shaping. p.782.
Depth [0…100]
Sets the tremolo modulation depth.
Source [Off…Tempo]
Selects the modulation source for the tremolo modulation
depth.
Amount [+/–100]
Sets the modulation amount of the tremolo modulation
depth.
LFO
L/R Phase Type [Phaser - Tremolo,
Phaser - Tremolo Spin,
Phaser - Tremolo LR,
Phaser LR - Tremolo,
Phaser LR - Tremolo Spin,
Phaser LR - Tremolo LR]
The phaser and the tremolo are both stereo, and each has its
own stereo LFO. This parameter controls the stereo phase
relationships of the LFOs within the individual effects.
There are two options for the Phaser, and three options for
the Tremolo, as described below. The menu selections set
both simultaneously.
Phaser: the phaser’s left and right LFOs are in phase with
one another.
Phaser LR: the phaser’s left and right LFOs are 180 degrees
out of phase, enhancing the stereo effect.
Tremolo: the tremolo’s left and right LFOs are in phase with
one another, causing simple amplitude modulation without
stereo panning.
Tremolo Spin: the tremolo’s left and right LFOs are offset,
causing the sound to appear to spin around the listener.
Tremolo LR: the tremolo’s left and right LFOs are 180
degrees out of phase, causing the signal to pan between the
left and right channels.
Phaser/Tremolo Phase [degrees] [–180, –90, 0,
+90, +180]
This lets you offset the phase between the phaser’s LFOs and
the tremolo’s LFOs. The result is that the peaks of the phaser
and the amplitude modulation or panning of the tremolo will
overlap in different ways, altering the sensations of
movement and rotation in the sound.
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…300.00]
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 779.
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 779.
