For FabFilter One, we have put tremendous effort in creating the best cut-off filter ever. Our new design approach has resulted in the fattest and smoothest self-oscillating digital filter you have ever heard.
It has been tuned carefully to achieve the character and warmth of a classic analog synthesizer. FabFilter One’s filter sounds raw but never cheap or ‘digital’, even at full resonance.
The filter is fed by an equally high-quality solid-sounding oscillator, developed from scratch to be completely aliasing-free. It features sawtooth, triangle, and square wave forms with pulse width modulation.
The oscillator and the filter can be modulated by the LFO and the EG. The LFO offers triangle and square wave forms, with adjustable wave balance so any wave form between sawtooth and triangle can be selected.
The tempo can be synchronized to the host. The EG has the usual ADSR knobs, but with a perfectly fine-tuned feel. Also, it has an additional Hold setting that extends the time keys are held down.
Naturally, the FabFilter One plug-in handles all parameter changes at sample accuracy and it can be used with arbitrary sample rates. All parameters are fully automatable within your favorite host and via MIDI Learn. The included help file describes all features of FabFilter One in detail, together with overviews and tutorials to create various types of sounds.
I was really impressed with the cutting sound [of FabFilter One]! It seems perfect for my in-your-face style of music, with plenty of scope for tweaking sounds to create mayhem!
