Tweak the filters with Simplon's large interactive filter display that shows both filter curves and lets you drag them around. In combination with the response and slope settings, FabFilter Simplon offers up to 27 different filter types. They range from smooth filters with moderate overdrive to raw, self-oscillating over-the-top madness! Simplon's filters sound raw but never cheap or ‘digital’, even at full resonance.Įach filter offers three different filter characteristics that define the unique sound and overdrive of the filter. Originally developed for FabFilter One, Simplon's filters were designed from the ground up to be the fattest and smoothest self-oscillating digital filters possible.
