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.

Got GAS? Hi, I'm Nico. I play guitar, so I buy guitars... and amps... and pedals... and for years, I've been looking for an app like this. So I finally decided to make one. With GASlist, you can log every guitar, bass, amp, pedal, synth, or drum kit you own — with photos, detailed specs tailored to each type of gear (all the geeky stuff that actually matters to us, this is honestly what took me the most time but I think it was worth it), the serial number, and your estimated value. This is the Gear section. What makes GASlist different — and IMO makes it the best app to track your gear (but I'm obviously not objective) — is the Rigs section. Build a rig for each of your musical projects and always know what gear you're using and who you're using it with. You can also keep all your project info in one place: upcoming shows and rehearsals, locations, setlists, band riders, and more. At any time, you can export a clean PDF catalog for each item or your entire collection. Flex on your bandmates, properly insure your rig (because yes, there's a specific place in each entry to store the purchase invoice), or just send it to that person who asked for more info because you just put a piece of gear up for sale. WHAT'S INSIDE Log guitars, basses, and a genuinely absurd list of stringed instruments — 9-string electrics, baritones, microtonal double-neck guitar/basses, lap steels, electric sitars, you name it — as well as pedals, synths, and drums. Track everything you own with the specs that actually matter (the nerdy stuff, but we know it's actually important). Build rigs from your gear. Snap up to 3 photos per entry for free, or up to 10 with Premium — because one angle never does a two-tone sunburst finish justice. Choose between dark and light mode. Export a shareable PDF catalog or a full JSON backup. Works offline — your collection shows up even when the venue Wi-Fi doesn't. Sign in with Apple and sync across every device you own (we know it's more than one). GASLIST PREMIUM Unlimited instruments, amps, and pedals. Unlimited rigs. Up to 10 photos per entry. Search your entire stash. Basically: no more excuses, no more limits — just more GAS. PRIVACY No ads. No tracking. Your gear, your data, your business. Export or delete it whenever you want. I'm just a musician, so there's no shady stuff. Actually, it's made by a musician, for musicians.
