Overview
The FabFilter One interface is divided into several sections, somewhat like
the front panel of a traditional analogue synthesizer.

- Oscillator
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 generator.
- Filter
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
- 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.
- Modulation generator
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!
- Additional features
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 cut-off frequency.
- Presets
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.
