Amazing Soft Synth Value!

Get to know them!

Carefully tuned to give you the character and warmth of a classic analog synth, the FabFilter One polyphonic synthesizer plug-in rocks just one oscillator, but it packs a punch with 10-voice polyphony, fine-tuned controls, scrumptious sonics, and a killer filter. The oscillator, with its sawtooth, square (with pulse-width modulation), and triangle waves, was developed to be totally free of aliasing artifacts. And then there's that filter: FabFilter worked long and hard to create the best digital highpass filter possible; indeed, it's among the sweetest we've heard here at Sweetwater - organic and raw, but never chintzy - even when you've dimed the resonance. And yes - you can drive it into self-oscillation.

Robust modulation options, and more

You can modulate both the oscillator and filter with One's LFO and envelope generator. The EG offers fine-tuned ADSR controls, and features an additional Hold setting that extends the time keys are held down. One also has portamento with a custom algorithm that juices your playing with enhanced expression. Featuring FabFilter's Smart Parameter Interpolation, One deals with all parameter changes at sample accuracy for smooth, responsive transitions, and you can use it with arbitrary sample rates. What you don't get are irksome digital clicks and zippering - even MIDI controller changes are handled smoothly. All-in, you'd be hard pressed to find a better soft synth value than FabFilter One.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
