Filterstation 2 is the Audio Damage dual filter, built for sound design and performance rather than corrective EQ. It runs two resonant filters in series, in parallel, or split across the stereo field, with twelve filter algorithms and a full set of modulation tools for movement, distortion, and rhythm. FEATURES Twelve filter algorithms, including our 914 bandpass and Filterpod lowpass models, a clean state-variable filter, and an MS20-style filter, covering lowpass, highpass, bandpass, and notch. Each of the two filter slots can run a different one. Serial, parallel, and true stereo routing. Run the filters one into the next, side by side, or split hard left and right. Envelope follower with stereo sidechain. Drive the cutoff from a signal's own dynamics for auto-wah, or feed in an external source so one track opens the filter on another. LFO with twelve patterns, internal or tempo-synced. VCA mode for tremolo and gating. FSU section for extra signal hacking, for when clean is not the point. Resizable vector interface, sharp on every iPhone and iPad display. Universal preset system. XML-based presets move between iOS and the desktop versions. IN USE... Sweep the cutoff by hand for filter rises and drops. Set the envelope follower to track the input for an auto-wah that moves with your playing. Patch a kick into the sidechain to duck a pad or bassline in time. Run the two filters in series for steep formant shapes, or in parallel for wide dual-band sweeps. Tempo-sync the LFO for rhythmic gating, then bring in the FSU section when the part needs to fall apart. Filterstation 2 runs as an AUv3 plugin inside any compatible iOS host, including AUM, Cubasis, Drambo, apeMatrix, and GarageBand. It is also available for macOS, Windows, and Linux as a desktop plugin, and presets move freely between them. Requires iOS 13 or later. An AUv3 host app is recommended. Features • Twelve different filter algorithms, including MS20 emulation and our classic 914 bandpass and Filterpod lowpass models. • VCA mode for tremolo and gate effects. • LFO with twelve different patterns, and both internal and tempo sync modes. • Envelope follower for dynamic control of filter frequency. • Serial, parallel, and true stereo operating modes. • Easy-to use interface for quick programming. • Vector-based resizable GUI. Use just the filter screen, slide the controls over it, or (in hosts that allow it) open up the whole UI. • Cross-platform XML-based preset manager; copy your desktop presets to the iOS version using Handoff, or share them with your friends and in forums. • Full PDF manual available at Support link.

CrushStation is an overdrive/distortion effects plug-in with controls that drive your tone anywhere from a creamy saturation to a brutal sonic assault, with everything in between. Originally from the Eventide H9 Harmonizer pedal, CrushStation has been refined for experimentation on numerous sound sources from your iPhone or iPad. Crush some octaves into the mix, or turn up the Sag to bring the whole sound to its knees. An added bonus, CrushStation is a true stereo distortion. CrushStation is an extremely versatile plugin, capable of adding spice and flair to a variety of production styles. Perfect for drum dirt, the Grit control adds preamp-style distortion that can help bring out kicks in the mix. Vocals benefit from the subtle distortion along with lower octaves for unique pitch blending effects. Further fine tune your sound using the three-band EQ which can help tame cymbals and vocal sibilance. Sure it rips for guitars and basses, but when you need a little warmth and saturation, add gusto to any synth. Features: - DRIVE ranges from subtle boost/overdrive to full on distortion with GRIT and SUSTAIN controls to push it into fuzz territory. - Unique SAG control - inspired by the result of power rail sag of dying analog gear - produces sputtering, crushed, and broken sounds. - Mix in lower and higher pitch-shifted OCTAVES, pre-distortion and compression. - GRIT creates low-end, gritty, chugging sounds. - Individual EQ controls to perfectly craft your tone, emphasize harmonics, or punch through the mix. - GATE your signal for taming the output of the distortion OR combine high threshold gating with MIX for parallel gated crunch. - The performance RIBBON provides real time, dynamic and fluid control to morph back and forth between the settings of your choice. - HOTSWITCH allows you to switch between two different distinct settings within the same preset at the push of a button. - Mixlock keeps the MIX constant so you can easily audition presets. - Available as an Audio Units AUv3 plug-in and Standalone App.
