022: Stereo Decimator
This effect creates a rough sound like a cheap sampler by
lowering the sampling frequency, reducing the bit depth, and
creating aliasing.
DECIMATOR
Pre LPF [Check-box]
If a sampler (or other digital audio device) tries to record a
pitch higher than half the sampling frequency, this generates
a particular kind of pitched noise, called aliasing. Reducing
the sampling frequency will tend to increase the amount of
aliasing.
Set Pre LPF to ON to prevent aliasing, or leave it OFF to
create aliasing artifacts.
To create a sound similar to a ring modulator, set the
Sampling Freq to about 3kHz and set Pre LPF to OFF.
Sampling Frequency [Hz] [1.00k…48.00k]
Sets the sampling frequency.
Source [Off…Tempo]
Selects the modulation source of the sampling frequency.
Amount [–48.00k…+48.00k]
Sets the modulation amount of the sampling frequency.
Depth [0…100]
Sets the depth of the sampling frequency LFO modulation.
Source [Off…Tempo]
Selects the LFO modulation source of the sampling
frequency.
Amount [+/–100]
Sets the LFO modulation amount of the sampling frequency.
High Damp [%] [0…100]
Sets the amount of high-frequency attenuation.
BIT SHAPE
Resolution [bits] [4…24]
Sets the data bit length. With lower settings, the sound may
be distorted, and the volume may increase. You can use the
Output Level parameter, below, to adjust the volume as
necessary.
Output Level [0…100]
Sets the output level.
Source [Off…Tempo]
Selects the modulation source for the output level.
Amount [+/–100]
Sets the modulation amount of the output level.
LFO
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.
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 762.
