• The noise generator: the noise signal produces acoustic energy across a broad
spectrum of frequencies with no discernible “fundamental” or harmonic signature. For
this reason, the noise module is used to create different noises like the imitation of
wind or special effects. White noise is the richest of noises. Pink noise is also regularly
present on synthesizers. It is less rich in the high frequencies than white noise. In the
Jupiter-8V section, you will find the noise generator as a selectable waveform on OSC
2.
8.1.2 The Mixer
The audio signal generated by an oscillator (the waveform) is generally directed toward a
filter module (Voltage Controlled Filter).
With the mixer of the Jupiter-8V: you are able to set the volume between OSC1 and 2
with the “Source Mix” knob. The mixer has no modulation input. Therefore this setting is
to be done manually.

8.1.3 The filter or VCF
The audio signal generated by an oscillator (the waveform) is next generally directed to a
filter module or VCF (Voltage Controlled Filter). It is this module that we use to
control the sound by filtering (by removing or subtracting certain frequencies, which
explains the name given to this type of synthesis) the harmonics situated around a cut-
off frequency. It can be considered to be a sophisticated equalizer that reduces,
depending on the filter type, a range of frequencies of a sound.
The removal of undesirable frequencies at the cut-off frequency is not done suddenly but
progressively, depending on the filtering slope. This filtering slope is expressed in
