VCF (Voltage Controlled Filter)

The filter section is integral to the instrument's unique sonic character
and allows you to shape the sound of the oscillators by modifying the
harmonic content of their signals.
The Super 6's main filter is a 4-pole, 24 dB per octave, analog resonant
low-pass filter that uses a classic polysynth filter design by Sound
Semiconductor (SSI). It is preceded in the signal chain by an analog high-
pass filter (HPF) that can either be turned off, set to a fixed frequency, or
track the low-pass filter cutoff frequency for band-pass operation.
The filter section.
The low-pass filter (LPF) subtracts frequency content above its cutoff
frequency. The frequency content below the cutoff frequency remains
unaffected, meaning the lows will pass through.
The high-pass filter (HPF) subtracts frequency content below its cutoff
frequency. The frequency content above the cutoff frequency remains
unaffected, meaning the highs will pass through. Using the high-pass
filter can be useful for removing 'muddy' low ends from pad sounds,
particularly in recording or mixing situations.
The Super 6 offers numerous options for modulating the low-pass filter's
cutoff frequency, making the filter section extremely versatile and suitable
for a wide variety of sounds.
Overall, the filter section of the Super 6 is divided into two: In the left
half you can adjust basic filter settings. The right half of the filter section
contains controls that affect how the low-pass filter is modulated by
different modulation sources and how it responds to key tracking.
