PSP stompFilter is a creative tool designed to provide an exceptionally wide range of modulated filter and gain sounds (VST, AAX and RTAS for Windows; AudioUnit, VST, AAX and RTAS for Mac OSX). Its effects include a simple LFO-modulated low pass filter; auto-wah; low-, band-, or high-pass filter; and compressor. Thanks to the smoothly adjustable filter type and flexible cross-modulations of the LFO by the envelope of the signal, PSP stompFilter is able to provide vivid, expressive filtering. Just a pinch of adjustable LFO randomization will provide analog-like "imperfections," ensuring that you will never get bored of it.
