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.

BLEASS Saturator is a creative saturation and distortion toolbox that lets you stamp your authority all over your audio. Roast your basses, crush your drums, and make your leads explode from a mix, all from the relaxing comfort of the plugin’s colourful and intuitive interface. The Drive module introduces analogue-style overdrive into your signal, from a gentle warming all the way to a veritable roasting. The module’s built in EQ allows precise control over the tonal character of the saturation as well. The Waveshaper distorts your audio using a second waveform. The way this happens depends upon the waveshaping algorithm that is used – BLEASS Saturator has nine to choose from. The algorithm has a significant impact on the character of the distortion that is produced. With its clear visualisation, and detailed-but-intuitive control over key parameters of the waveshaping algorithms, the Waveshaper module offers a near infinite choice of sonic colourations and distortions. BLEASS Saturator’s Bit module simulates the distortion characteristics of analogue-to-digital conversion. We’re all familiar with the pristine sound quality that is produced when both sample rate and bit depth are suitably high, but dragging these values down can create wonderful glitches and distortions that are fundamentally digital in character. Further creative possibilities are presented by the option of applying the Bit module either before or after the Waveshaper module. The built-in LFO can be routed to any of the plugin’s parameters, and can be synced to the host’s beat and tempo. This allows you to explore evolving, shifting and rhythmic distortions that would be hard to achieve with conventional saturators. Gentle settings can create pleasingly warm and fuzzy results, but despite its small footprint and lightweight CPU usage, BLEASS Saturator has the strength to hit your audio like a ton of bricks!
