FabFilters Simplon is a simplified version of the Volcano 2 and offers two independent multimode filters with low-pass, high-pass and bandpass functions, as well as 12/24/48 dB/oct. slopes. The filters can be switched in series or in parallel mode. A combination of the different response and slope settings results in a total of 27 different filter types. Tweak the filters with the large interactive filter display that shows both filter curves, which you can move by dragging and dropping - even simultaneously.

And of course you also get all the usual FabFilter goodies: perfectly tuned knobs that work in both vertical and circular drag mode, interactive MIDI Learn, Smart Parameter Interpolation for smooth parameter transitions, great presets, extensive help files with interactive help notes, sample-accurate automation for all parameters, AltiVec and SSE optimization and much more.
