ADDAC System ADDAC112SF (2021–)
A powered desktop shell that turns a Eurorack looper into a standalone workstation
Overview
The ADDAC112SF doesn't make a sound and doesn't process audio. It is a 45HP powered desktop frame built for one job: letting the ADDAC112 VC Looper and Granular Processor run outside a Eurorack case. That frees the CV-heavy granular engine from the modular rig. You can set it on a café table, plug in a microphone, loop a passing train, and start breaking it into particles before your coffee gets cold.
ADDAC System, the Portuguese outfit known for its hands-on approach to modular synthesis, designed the ADDAC112SF as a home for the ADDAC112. The 112 is a dual-module unit that combines a 5-minute voltage-controlled looper with a full-featured granular processor. Without this frame, it needs a Eurorack case, a power supply and patch cables just to work. The frame takes power from an external adapter, gives the module a clean mount, and keeps all the I/O accessible on one side. That suits live performers, field recordists, or anyone who wants granular synthesis without the rack.
The frame isn't where the magic is. The ADDAC112 is the real star, and it has so many features it borders on being a Eurorack DAW in miniature. It has a high-resolution OLED display, dedicated mix controls for dry, looped and granular outputs, and deep CV integration. It's one of the most intuitive granular tools in modular synthesis. The 112SF adds no functionality. It just removes the friction of needing a rack.

Key Features
A Frame That Frees the Module
The ADDAC112SF is a compact, no-nonsense enclosure made from black powder-coated steel. It holds the ADDAC112 securely and keeps all front-panel controls and patch points accessible. It includes an external 12V power supply, so all you need to get started is the module and a place to put it. There are no rack ears and no options for Eurorack integration. This is strictly a desktop solution. By removing the need for a case, power distribution and cabling, ADDAC turned a modular-only processor into a portable audio instrument.
Optimized for Performance and Patching
Every design choice in the 112SF goes toward usability. The module is mounted at a slight angle, which improves visibility of the OLED screen during live performance. The rear panel routes all I/O to a single zone, so patch cables stay tidy and put less strain on the jacks. The frame is just 55mm deep, so it fits on crowded desks or in travel cases. It's shaped specifically for the ADDAC112, so there's no wasted space or awkward overhang. The finish resists fingerprints and minor scratches, which helps on something handled regularly.
The Gateway to Standalone Granular Synthesis
Most granular modules demand a full modular system to be useful. Pair the 112SF with the ADDAC112 and you get a standalone granular workstation that records, loops and mangles audio with the same depth as any rack-based setup. You can plug in a microphone, guitar or line-level source, capture a loop, then slice it into grains with voltage control over pitch, density, position and randomness. The waveform and grain placement show on the OLED display the whole time. Loops and presets save to SD card, so you can show up with a library of textures ready to go.
Historical Context
The ADDAC112SF arrived in 2021, as Eurorack was developing a growing appetite for standalone functionality. For years, modular synthesis stayed insular: to use a module, you needed a case, power, and a patch cable for everything. Modules then got more complex, especially digital ones with screens, storage and internal processing, and using them outside a rack started to make sense. The ADDAC112 was one of the first granular modules to offer this level of autonomy. The 112SF was ADDAC's answer to the obvious question: "Can I use this without a case?"
At the time, competitors like Mutable Instruments' Beads and Qu-Bit's Nebulae required Eurorack integration and offered less hands-on control. The ADDAC112, by contrast, felt more like a software granular engine translated into hardware, with dedicated knobs for nearly every parameter and a display that showed grain placement in real time. That complexity came with a cost: 45HP of space and a steep learning curve. The 112SF didn't reduce the cost, but it did lower the barrier to entry. It fit a wave of semi-modular and desktop Eurorack products from companies like Make Noise, Intellijel, and Critter & Guitari, all trying to make modular ideas more accessible. The 112SF wasn't the first of its kind, but it was one of the most focused - a single-purpose frame for a single module.
Collectibility & Value
The ADDAC112SF can't be bought on its own. It's only available as part of a bundle with the ADDAC112 module, so its collectibility is tied entirely to demand for the 112. As of 2026, the complete ADDAC112 + 112SF system typically sells for between $800 and $950 on the used market, depending on condition and included accessories. Units with the original power supply and packaging hold more value, especially given the difficulty of sourcing a replacement frame.
The 112SF is a passive enclosure, so it has no serviceable parts and almost no failure points. The main concerns are cosmetic: scratched panels, loose mounting screws, or bent jacks from rough handling. The real risks are in the ADDAC112 module itself, which has been known to show firmware instability, especially in early production runs. Some users report crashes or SD card read errors, though firmware updates often resolve these. Before buying, test the SD card slot, verify that all knobs and buttons respond, and confirm that the OLED display is free of dead pixels.
For collectors, the 112SF sits in a niche but growing category of modular gear that works outside the rack. It's not rare, but it's not common either. If you see one listed without the ADDAC112 module, be skeptical, since there's little demand for the frame alone. The 112SF bundle is a portable granular looper with deep CV control and real-time visual feedback. It isn't the cheapest way into granular synthesis.
