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.Requirements:PCVST3• Windows x32 or x64 (7, 8 or 10)• VST3 compatible applicationVST• Windows x32 or x64 (XP Service Pack 2, Vista, 7, 8 or 10)• VST 2.4 compatible applicationRTAS• Windows x32 or x64 (XP Service Pack 2, Vista or 7)• ProTools LE 8.0.0 or ProTools TDM 8.0.0 (or later)AAX• Windows x32 or x64 (XP Service Pack 2, Vista or 7 or 8 or 10)• Pro Tools 10 or Pro Tools 11 or Pro Tools 12 (or later)Mac (intel)AudioUnit• Mac OSX 10.6 - 10.11 or later• 32 or 64-bit host application capable of running AudioUnit plug-ins with Cocoa viewVST• Mac OSX 10.6 - 10.11 or later• 32 or 64-bit VST 2.4 compatible host applicationVST3• Mac OSX 10.6 - 10.11 or later• 32 or 64-bit VST 2.4 compatible host applicationRTAS• Mac OSX 10.6 - 10.11 or later• ProTools LE 8.0.0 or ProTools TDM 8.0.0 (or later)AAX• Mac OSX 10.8 - 10.11 or later• Pro Tools 11,12 or later
