FabFilter Twin 2 Help
FabFilter Twin 2 comes with three full featured oscillators. Combined with our award winning filters this gives you an exceptional broad palette of sounds. The oscillators are very analog sounding and completely aliasing-free (for the digifoobs!). For every oscillator the following parameters are available:
This will turn an oscillator on or off, so you can easily check the contribution of an oscillator to the overall sound, or turn it off to reduce CPU usage.
Each oscillator can be transposed up to 3 octaves above the master tune.
The Waveform parameter selects the waveform that the oscillator produces:
Next to the waveform setting, the Phase Sync button (with a MIDI icon) toggles oscillator phase sync on and off. When oscillator phase sync is on, the oscillator resets its phase to halfway the waveform on each note-on event. With short, percussive sounds, this works really well to create a sharp and aggressive attack with every note. However, normally you should turn it off because it sometimes introduces unwanted clicks.
The Detune knob sets the detune for each oscillator. The detune knob has a range of +/- one octave, and is extra sensitive around the 0 position. It is a modulation target as well. Like any other knob, you can double-click it to enter a value directly using the keyboard. For example, try '0.5 octaves' or '1 semitone' or '50 cents'. See Knobs for more information.
The Pulse Width knob adjusts the pulse width of the square waveform, from an even square to an infinitely thin pulse (which is actually inaudible). The pulse width is a modulation target and is only available when a square wave is selected.
The Sync knob adjusts the level of hard sync for its oscillator. When set to 1, the oscillator works normally without hard sync. When set to a higher value, the oscillator will 'squeeze' more phases into one actual audible phase, which drastically changes the harmonics in the sound with a metallic-sounding effect. Sync is a modulation target.
The volume and pan of each oscillator can be adjusted using the combined Level/Pan knobs. The inner knob set the overall level and outer ring sets the panning. Both are modulation targets.
You can ring modulate the first oscillator with the second oscillator using the small * button between the component buttons for oscillator 1 and 2. Ring modulation combines two waveforms, and outputs the sum and difference of the frequencies present in each waveform. This produces a signal rich in overtones, suitable for producing bell-like or otherwise metallic sounds.
The Master Tune knob determines the global frequency offset of all oscillators. The menu above the knob transposes the frequency by full octaves. The Master Tune knob is a modulation target so you can modulate the frequency of all oscillators at once.
The Portamento knob adjusts the amount of portamento or glide, which makes the oscillators slide from one note to another. A little portamento is great for smooth keyboard solos, or when playing large bass intervals. Good portamento is one of those things that give your play just that little bit extra: it's magic. So we have fine-tuned it until it was just perfect! The best thing is: we have created a unique portamento because it also works in polyphonic mode, so you can play sliding chords. You can choose between two different portamento modes.
When using Normal portamento (high/low key portamento), gliding will happen always when holding down keys.
When using Legato portamento (also called fingered portamento), gliding will not be applied for the first key pressed, only for the keys after that.
Portamento is also a modulation target.
When you want to change any oscillator parameter for all oscillators at the same time, just hold down the Alt key while turning a knob.
Each oscillator is visually represented as a component button. By clicking on the component button and dragging, you can directly alter the most important oscillator parameters:
Click on a button to open the full oscillator interface (shown in the screen shot above) that provides access to all parameters. For other component shortcuts, see Component buttons.
