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 ratio of cut of the high range.
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…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.
