Overview

FabFilter Twin's interface is divided into three sections. The upper section contains the oscillators and filters, together with general settings such as portamento, volume and stereo spread. The bottom section contains the modulation sources such as the three LFOs and three envelope generators, and general MIDI and polyphony settings. The middle section contains 24 modulation slots which can be used to modulate almost any parameter with any modulation source.

• Top section
  The two oscillators and the noise oscillator are the heart of the synthesizer, producing the raw tones that are modified by the other components. The multi-mode filters alter the tones from the oscillators to make them warmer and less harsh, or to add various effects. Like true analogue filters, they can easily be driven to self-oscillation to create completely distorted sounds, or a warm lead with a little raw edge. The oscillators and filters can be routed in serial, parallel of per-oscillator mode. Most of the oscillator and filter parameters can be modulated by FabFilter Twin's modulation sources. At the far right, there is an output section with volume and stereo spread settings.
• Middle section
  The middle section contains 24 modulation slots, of which 8 are visible at a time. For every modulation slot you can specify a source, a target and a modulation level. Also, the modulation signal can be inverted or temporarily disabled. The easiest way to work with the modulation slots is by using drag-and-drop.
• Bottom section
  The bottom section contains the modulation sources. First, there are three LFOs and three envelope generators. The envelope generators offer delay, hold, attack, decay, sustain and release settings and an offset option. The LFOs have adjustable sine, triangle, square, random triangle and sample-and-hold wave forms and can be synchronized to the hosts beat and tempo. Other modulation sources are: velocity, aftertouch, keyboard track, modulation wheel, and pitch bend. For every source, there is a source icon, which can be dragged to any target knob in the interface. MIDI Learn offers the possibility to easily associate any controller with any plug-in parameter. Finally, different polyphony and unison settings which give you the possibility to create super-fat sounds.
• Presets
  With the preset buttons, you can easily browse through the factory presets or save your own sounds so you can re-use them in other songs. See Presets.
