The Silver Bullet mk2 Plugin is a faithful digital recreation of our flagship Silver Bullet mk2 hardware unit. We meticulously modeled every analog circuit down to the component level. To push the state of the art further, we developed a new patent-pending technology called Dyna Realism™, allowing users to experience an inspiring spectrum of analog realism in the digital domain. Use the three cascading Mojo Amps, powerful Tone Shaping EQ, and no-fuss ASPECT RATIO stereo image enhancer to sweeten and glue your mix bus, groups, and individual tracks in the DAW. The plugin accurately reproduces the harmonically exciting sound of the original while adding extra features that extend its versatility. Explore new digital Colour modules and Circuit Bending options exclusive to the plugin. A MODERN ANALOG CLASSIC – NOW DIGITAL The Silver Bullet mk2 Plugin is a results-oriented processor with an intuitive interface designed to deliver amazing tone like its analog counterpart so you can focus on making music. Engage MOJO. Apply filtering, tone shaping, and stereo image enhancement. Delight in how easy that was. CASCADING MOJO The 3-band Baxandall EQ features a Pultec-inspired low end and smooth, expensive-sounding top end worthy of renowned mastering EQs. The beloved AIR circuit now has its own dedicated control. Tighten extreme low end with the TIGHT filter. The resonant, tape-like 25 Hz setting excels on mixes, while the 50 Hz setting is optimized for individual instruments. Smooth digital top end with silky VINTAGE mode inspired by legendary 1970s British consoles. TONE SHAPING The original LF and HF frequency options have been expanded to four frequencies per band. AIR now has its own control for even greater flexibility. STEREO IMAGE ENHANCEMENT ASPECT RATIO enhances stereo width, height, and clarity without the phasey artifacts of many widening effects. ASPECT RATIO delivers masterful results at the touch of a button. No fussy tweaking required. CUSTOMIZE MOJO WITH C MOJO / COLOUR The plugin includes the hardware expansion slot plus exclusive modules developed with Unfiltered Audio: Hitmaker 4000 – 1980s VCA console saturation Bitmaker 1200 – 12-bit sample-rate-reduced console character inspired by late-80s samplers Vinyl Saturation – warm vinyl saturation based on Needlepoint Helical Scan – VHS-inspired warble based on LO-FI-AF VHS AF – combines Vinyl Saturation and Helical Scan Hitmaker Comp – Mix Lord, Punch, and Gentle compressor modes WHAT IS ANALOG? Our goal was to capture the essence of analog, including variations, idiosyncrasies, imperfections, and delightful surprises. Every circuit was modeled down to the component level and enhanced with Dyna Realism™. DYNA REALISM™ Dyna Realism™ uses our Virtual Parts Bin and Serial Number systems to construct unique static and dynamic circuit models across a spectrum of variation and realism. Each setting reveals increasingly rich variations within and between channels, bringing life to static emulations. SERIAL NUMBERS Every plugin instance receives a unique built-to-order digital circuit associated with your license. The rear-panel serial number is functional and influences Dyna Realism™ behavior. Enter any number sequence to alter your build. CIRCUIT BEND Virtually hack the circuits without risk. BEND 1 and BEND 2 short power rails in different processing areas to create distorted and broken textures for creative exploration.
AU Studio
This app acts as a dedicated host for Audio Unit extensions, allowing musicians and developers to inspect, audition, and test installed audio plugins. It provides detailed information about each unit's capabilities and behavior without requiring a full digital audio workstation.
- Scan and catalog installed Audio Units
- Filter plugins by developer, type, and status
- Load AUv3 interfaces or use detailed inspector
- Inspect registry identity, MIDI support, and parameters
- Route CoreMIDI sources and audition audio effects
- Monitor runtime CPU and memory usage
- Built-in manual for guidance

AU Studio is a focused Audio Unit host, not a DAW. Open the plug-ins you already own, hear them in seconds, and see exactly what they expose. Made for musicians, sound designers, and Audio Unit developers who need a fast, honest test bench. No session to build, no tracks to arm. Pick a unit from your catalog and its interface opens in a panel of its own, named and sized to the plug-in, with your host controls in a bar above it. Key features: - Scan the instruments, effects, music effects, generators, and MIDI processors already installed on your device: AUv3 on iPhone, iPad, and Apple Vision Pro, plus AUv2 on Mac. - Filter by developer, type, or search text, and hide Apple built-ins to focus on third-party gear. - Open a plug-in's own interface when it ships one, and fall back to a metadata view when it doesn't, with the full inspector always one tap away. - Inspect identity, four-character codes, version, sandbox and cached validation status, MIDI support, busses, parameters, presets, latency, and tail time. - Step through factory presets, then save your own working state without leaving the interface. - Play instruments from the floating MIDI keyboard: notes, pitch bend, mod wheel, auto, mono or poly voicing, a shiftable range, and one-tap panic for stuck notes. Your hardware controller lights up the on-screen keys as you play. - Run a guitar, a microphone, or any channel of your interface through a loaded effect. Pick the device, pick mono or stereo, pick the channels. - Load a track into the floating media player, scrub the waveform, loop a section, and play along with your live input at the same time. - Check a signal path in seconds with the built-in test tone. - Route external CoreMIDI sources in, and send generated MIDI back out to a CoreMIDI destination. - Test MIDI 2 units with automatic, MIDI 1, or MIDI 2 protocol selection: high-resolution notes, registered and per-note controllers, per-note pitch bend, discovered MIDI-CI Profiles, and a monitor showing raw or decoded MIDI going in and coming out. - Choose your output device on Mac, and set sample rate, buffer size, and which MIDI sources are enabled. - Keep host-process CPU and memory in view while you work. - Open unfamiliar plug-ins with less risk. AU Studio asks first when the system does not mark a unit sandbox-safe, and a peak limiter sits across the host output. - Read the built-in manual, fully searchable: discovery, routing, presets, hardware input, floating tools, troubleshooting, and developer notes. What AU Studio is: A focused host for discovering, opening, auditioning, and inspecting the Audio Units already on your device. It answers the practical questions: Is the unit visible? Does it load? Does it have an interface? What busses, parameters, presets, and MIDI capabilities does it expose? Does MIDI reach it? Does audio pass through it? What AU Studio is not: It is not a DAW. No multitrack recording, clip launching, timeline arrangement, piano-roll sequencing, MIDI learn, automation lanes, song export, or mastering tools. AU Studio ships no Audio Unit of its own — no instrument, no effect, no DSP engine. It hosts the units other apps provide and wraps them in host-owned routing, auditioning, and inspection. Discovery uses the system Audio Unit registry. If a provider app is not installed, not enabled, or not visible to the platform, AU Studio cannot invent it. Interface behavior, presets, parameter meaning, MIDI mapping, and DSP results belong to each Audio Unit.
