FabFilter Saturn contains one set of controls to adjust the currently selected frequency
bands. When only one band is used, it will be selected by default and the controls are automatically linked to that single band. Once you have multiple
frequency bands available, the display highlights the level buttons of the selected bands and
they are linked to all of them.
From left to right, the following parameters are available:
The Enabled button lets you easily bypass the selected frequency bands.
When bypassed, the dry input signal of the band is passed to the output straight away. Note
that you can also solo and mute bands with the solo/mute buttons in the display.
The Section Preset button lets you quickly save or restore the parameters
for the selected bands. See Section presets.
The Mix sets the combination of unprocessed (dry) signal and the
processed/distorted signal for the band.
The Feedback Amount knob sets the level of feedback for the band, which
feds the processed audio back into the input of the band. The Feedback
Frequency knob sets the ringing frequency of the feedback loop. You can simply compare
this to the distance of a microphone which picks up the signal of an amplifier that outputs its
own signal: the closer the mic gets to the speaker, the higher the ringing frequency.
The Dynamics knob can be used to either gate or compress the band signal.
Turning the knob to the right will add heavily pumping compression, while turning the knob to
the left will introduce great all-purpose gating/expansion.
The Style button selects the type of distortion applied to the signal. You
can choose between:
Tube emulations: from clean, high quality tubes to juicy or even
broken tube sound.
Tape emulation: subtle, warm or extreme tape saturation.
Amplifier emulation: from smooth and crunchy amplifiers to screaming
Smudge: This creative distortion algorithm smudges and stretches the
audio in weird and unexpected ways. The Drive knob sets the amount of
Rectify: A crunchy combination of rectified sound, DC offset removal
and soft clipping.
Destroy: A destructive combination of bit-crushing, sample rate
reduction and clipping.
The Drive knob is obviously one of the most important parameters, setting
how much the clipping stage is driven with input signal. While increasing the drive, the output
level will be adjusted automatically, to ensure that the overall sound level doesn't get out of
control. With the pan ring, you can change the balance of the drive amount
between the stereo channels (see also Mid/Side
The Tone controls set the bass, mid, treble and presence of the processed
band signal, allowing you to tweak the harmonics generated by the distortion algorithm.
The Level knob sets the output level of the selected bands between minus
infinity and +36 dB. With the pan ring, you can change the relative levels of
the left and right audio channels (or mid/side when Mid/Side processing is active).
The Remove button deletes the currently selected bands.
All continuous band parameters can be modulated, of
When adjusting band settings with a continuous range (for example Drive, Level, Dynamics)
for multiple selected bands at once, the relative differences between the bands will be
preserved. When adjusting discrete parameters (HQ, Distortion Style), the parameter for all
bands will be set to the same new value. If you double-click a knob to enter a value, this
value will be applied to all bands directly as well.
