FabFilter Simplon is a streamlined version of FabFilter Volcano 2 with two independent multimode filters that provide low-pass, high-pass, and band-pass responses with 12/24/48 dB/octave slopes. The filters can be used in series or parallel.

Originally developed for FabFilter One, Simplon's filters were designed from the ground up to be the fullest and smoothest self-oscillating digital filters possible. Simplon's filters sound raw but never cheap or 'digital', even in full resonance.

Each filter offers three different filter characteristics that define the filter's unique sound and saturation. They range from smooth filters with moderate overdrive to over-the-top self-oscillating madness!

In combination with the response and slope settings, FabFilter Simplon offers up to 27 different filter types.

Modify the filters with Simplon's large interactive filter display, which shows both filter curves and lets you drag them. You can adjust the filters separately or both at the same time.

And, of course, you get all the usual FabFilter benefits: perfectly tuned knobs that work in both vertical and circular drag modes, interactive MIDI learning, smart parameter interpolation for smooth parameter transitions, excellent presets, an extensive help file with interactive help suggestions, precise sample automation for all parameters, AltiVec and SSE optimization, and much more.
