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.
