The FabFilter One interface is divided into several sections, somewhat like the front panel of
a traditional analogue synthesizer.
The oscillator is the heart of the synthesizer, producing the raw
tones that are modified by the other components. It also contains portamento, additional noise
settings and settings that control the amount of frequency modulation by the modulation generator and envelope
The filter alters the tones from the oscillator to make them warmer
and less harsh. Like a true analogue filter, it can easily be driven to self-oscillation to
create completely distorted sounds, or a warm lead with a little raw edge. The filter section
also contains settings that control the amount of frequency modulation by the modulation
generator and envelope generator
The final touch and feel of the sound is defined by the envelope generator. Tweak the various settings here to create
anything between short percussive hits to long reverberating effects.
The modulation generator generates a low-frequency square
or triangle wave that can be used to modulate both the frequency of the oscillator and the
cut-off frequency of the filter. This is where the fun starts!
This section contains a few useful extras. You can choose between monophonic and polyphonic
(10-voice) mode, set the type of pulse width modulation, set the amount of filter keyboard
tracking and set the amount of keyboard velocity modulation for the volume and the filter
With the preset button, you can easily browse through the factory presets or save your own
sounds so you can re-use them in other songs. See Presets.
