018: Stereo Random Filter
This stereo band pass filter is modulated by an LFO, using
either a step-shape waveform and or a sample-and-hold
shape. The filter will also self-resonate, for creating special
effects.
FILTER
Manual
[0…100]
Sets the filter’s center frequency, before LFO modulation.
Depth
[0…100]
The LFO modulates the filter’s frequency; this sets the
intensity of the LFO modulation.
Source
[Off…Tempo]
Selects a source to modulate the LFO
Depth
.
Amount
[+/–100]
Sets the intensity of the
Depth
modulation.
Resonance
[0…100]
Resonance emphasizes the audio around the filter’s center
frequency.
At
0
, there is no emphasis, and frequencies outside the center
will simply diminish smoothly.
At medium settings, the resonance will alter the timbre of the
filter, making it sound more nasal or extreme.
At very high settings, the resonance can be heard as a
separate, whistling pitch. At
100
, the filter will self-oscillate
(after being fed an initial burst of input).
LFO
Waveform and Phase
Waveform
[Step-Tri, Random]
Step-Tri
creates a steppy triangle waveform (see the
diagram below). The
LFO Frequency
parameter sets the
original triangle waveform speed, and the
LFO Step Freq
parameter adjusts the width of the steps.
Random
produces a sample-and-hold waveform, with the
speed controlled by the
Step Freq
.
Phase [degrees]
[–18…+18]
This sets the LFO phase difference between the left and
right, in steps of 10 degrees. Offsetting the left and right
phases alters how modulation is applied to the left and right
channels, creating a swelling effect.
Frequency
These parameters apply when
MIDI/Tempo Sync
is
Off
(un-checked).
Frequency [Hz]
[0.02…20.00]
This sets the speed of the triangle waveform, in Hz.
Step Frequency [Hz]
[0.05…50.00]
This sets the speed of the steps, in Hz.
Source
[Off…Tempo]
This selects a modulation source for both the
Frequency
and
the
Step Frequency
. You can set the modulation amounts
individually, below.
Amount
[–20.00…+20.00]
Sets the
Frequency
modulation amount, in Hz.
Step Amount
[–50.00…+50.00]
Sets the
Step Frequency
modulation amount, in Hz.
MIDI/Tempo Sync
MIDI/Tempo Sync
[Check-box]
When this 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.
BPM
[MIDI, 40.00…300.00]
MIDI
syncs to the system tempo.
40-240
sets the tempo
manually for this individual effect.
Base Note
[
…
]
Times
[x1…x32]
These set triangle waveform’s base note and multiplier. For
more information, see “MIDI/Tempo Sync” on page 779.
Step Note
[
…
]
Times
[x1…x32]
These set the step’s base note and multiplier. For more
information, see “MIDI/Tempo Sync” on page 779.
