5.3 Noise Generator
On this page, you find the noise generator
controls. To open this page, click on the N
selection field in the left section. Each Layer
features its own noise generator.
•
Noise Activation
:
Click on this
button, to
activate/
deactivate the
Noise generator.
•
Noise Selection
:
Click on this pop-
up menu to select
the noise type.
You can choose
between White
noise (which contains all frequencies with equal intensity) and
Pink noise (where each octave interval carries an equal amount
of noise energy).
•
Noise Filter
: Click on the pop-up menu to select the desired
noise filter type. A description of the available filter types can
be found in chapter „5.7 Filter 1 and 2“.
•
Cutoff
: Controls the cutoff (on low pass or high pass types) or
center (on band pass or band stop types) frequency of the
filter. If Comb is selected, the frequencies near the cutoff
frequency are emphasized. If Redux is selected, the outgoing
sample rate of the signal is reduced. The Cutoff value is shown
in Hz ion the left section and also as graphical representation.
•
Resonance
: Controls the resonance of the filter if set to any of
the 12 dB or 24 dB filter types. On 6 dB filter types, this control
does nothing. On band stop types, it narrows the stop band,
which is almost inaudible. If Redux is selected, the outgoing bit
rate of the signal is reduced.
•
Burst Rate
(the upper parameter in the left section of the Noise
generator): Burst noise consists of sudden step-like transitions
between two or more current levels. The lower the value, the
more popping or crackling sound is produced.

Pitch LFO, Level LFO, Pitch Envelope, Level Scaling and Level
Envelope are described in separate sections in chapter 5.6,
because they are identical for all Operators/Sample Oscillators/
Noise generator.
