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.

The MF-104S Analog Delay is a re-invention of Moog Music’s classic Moogerfooger MF-104 analog effects pedal. The MF-104 Analog Delay, introduced in 2000, added a lush, all-analog delay to the classic line of Moogerfooger effects. It incorporated a dual-range Bucket Brigade Device (BBD) providing a range of delay times from 40 milliseconds to 800 milliseconds. Later versions of the MF-104 offered tempo synchronization, and extensive time modulation options via a multi-waveform LFO. Designed by Bob Moog and his engineering team, the MF-104 was a direct descendant of the original Moog modular synthesizers, adapted to process, modulate, and play with inputs ranging from guitar, voice, and synthesizer to any imaginable audio source. The MF-104 Analog Delay has been meticulously recreated as the MF-104S, capturing all of the warm, organic texture and character of the original analog delay circuitry, while adding 21st-century flexibility and ease of use. The MF-104S is an AUv3 effects plug-in that requires a compatible host or DAW to function.

Verdict
The clearest difference is review sentiment: Filterstation2 at 75% against MF's 0%. Filterstation2 also leads on price ($4.99 vs $14.99). MF's advantage is rating (5.0 vs 4.5) and update cadence (monthly vs every 19 months). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
