ADDAC System ADDAC112 (2021–)

A looper that thinks like a composer and granular processor that feels like painting with sound—deep, visual, and alive with voltage.

Overview

You don’t just patch the ADDAC112—you conduct it. From the moment you hit record and that 5-inch OLED lights up with a scrolling waveform, you’re not just capturing audio, you’re setting the stage for something that breathes, mutates, and responds. This isn’t a tucked-away granular module you forget about once it’s patched; it’s front-and-center, demanding attention with its split-panel design that separates the control brain from the patch bay, letting you tweak knobs without cables getting in the way. It’s rare to find a Eurorack module that feels like a standalone instrument, but the ADDAC112 pulls it off—less like a cog in a machine, more like a collaborator.

At its core, the 112 is a dual-engine beast: one half is a full-featured stereo looper with CV-controlled record, overdub, and loop selection, the other a granular processor that slices that loop into clouds, stutters, or shimmering textures. But the magic isn’t in the separation—it’s in how they feed each other. Record a drone, a beat, a vocal snippet, and then let the granular engine chew it up, scatter grains across the stereo field, pitch-shift them independently, or lock them to a scale. The real-time display shows every grain as a tiny dot dancing across the waveform, so you’re not guessing what’s happening—you’re watching it unfold. It’s like having a window into the soul of your audio, and once you’ve seen it, you can’t go back to blind granular processing.

Portuguese outfit ADDAC System has always leaned into the experimental, but the 112 feels like their most mature statement yet—a module that doesn’t just copy software workflows but reimagines them for the modular realm. Where other granular modules make you dive into menus or settle for abstract controls, the 112 gives you direct, knob-per-function access to nearly every parameter, from grain size and density to randomization of start point and pitch. And because nearly every one of those knobs has a CV input on the companion panel, you can modulate the chaos with precision. Want the grain spacing to swell with your envelope? Patch it. Need the loop start point to jitter with an LFO? Done. The separation of control and I/O isn’t just convenient—it’s transformative, letting you build complex, evolving textures without sacrificing hands-on control.

Key Features

The Dual-Panel Philosophy: Control vs. Connection

The ADDAC112 doesn’t just use space—it rethinks it. Instead of cramming jacks between knobs, ADDAC split the module into two physical panels: one dense with controls, the other a dedicated patch bay for all I/O. This isn’t just cosmetic; it changes how you interact with the module. You can place the patch panel off to the side or below your case, routing all your CV and audio connections there, while keeping the main panel free for performance tweaks. It’s a small design decision with massive usability payoff—no more fumbling for a knob buried under a cable. And because the patch bay includes CV inputs for nearly every parameter, you’re not sacrificing patchability for clarity. If other granular modules feel like black boxes, the 112 hands you the blueprint.

Visual Granular Synthesis That Makes Sense

Most granular modules make you trust your ears and hope your settings are doing what you think. The 112 hands you a map. The OLED screen doesn’t just show the loop waveform—it overlays the current grain positions as moving dots, so you can see how density, spacing, and randomness affect the texture in real time. Adjust the grain size and watch the dots stretch or shrink. Modulate the start point and see them slide along the waveform. It’s not just feedback—it’s insight. This visual layer turns granular synthesis from a trial-and-error process into a compositional tool. You can set up rhythmic stutter effects by clustering grains at transients, or create evolving pads by slowly drifting the playback window. And because the screen also shows loop selection, playback position, and scale constraints, it’s not just for granular—it’s your entire audio workspace at a glance.

Workflow That Rewards Experimentation

The 112 doesn’t lock you into one way of working. You can use it as a straightforward looper with CV start/stop, or as a live sampler that records and plays back with pitch control. But the real joy is in the hybrid mode: record a loop, then immediately start granulating it while still adjusting the source. Want to layer the dry input, the loop, and the granular output? Three dedicated mix knobs make it instant. Need to save a bank of loops for a live set? The SD card handles it, and you can recall banks via CV or front-panel knob. The menu system is minimal—mostly for saving/loading—and the encoder is used sparingly, so you’re never buried in submenus. It’s a module that respects your time, giving you deep control without demanding a PhD in patching to get results.

Historical Context

When the ADDAC112 launched in 2021, granular modules were already a staple of the Eurorack world—Mutable Instruments’ Beads had set the standard years earlier, followed by Qu-Bit’s Nebulae and Instruo’s Arbhar. But most leaned into abstraction, trading immediacy for flexibility. The 112 flipped that script. Instead of a compact, menu-heavy module, ADDAC went big—45HP of dedicated controls, visual feedback, and a workflow that felt more like a digital audio workstation than a modular effect. It was a bold move in an ecosystem where space is currency, but it paid off. The 112 carved out a niche for users who wanted granular processing that didn’t require constant menu diving or guesswork. It also reflected a broader trend in Eurorack: the rise of “desktop” modules that prioritized usability over density, appealing to performers and composers who wanted instruments, not just processors. In that context, the 112 wasn’t just another granular module—it was a statement that deep control and visual feedback could coexist in the modular world.

Collectibility & Value

The ADDAC112 isn’t vintage in the traditional sense—it’s too new for that—but it’s already gained cult status among modular users who value workflow and visual feedback. New units sell for around $699 or 620€, but the secondary market is tight, with used prices hovering between $600 and $750 depending on condition. Because it’s a relatively recent module, most units on the market are in good shape, but there are a few red flags to watch for. The firmware has evolved significantly since launch, with version 1.9 introducing performance improvements but reducing maximum loop time from 5 minutes to 3 minutes in stereo. Units running older firmware can load longer loops, but may lack newer features. Buyers should confirm which firmware version the module is running and whether it’s been updated properly—bricking during firmware updates is rare but possible, especially if the wrong USB cable is used (it must support data, not just power).

The most common issues reported are SD card corruption and occasional crashes, especially with beta firmware. These are generally resolved by reformatting the card or reloading firmware, but they’re worth testing before purchase. The OLED screen is robust, but like any display, it can fail—check for dead pixels or flickering. Physically, the module is well-built with sturdy knobs and jacks, but the dual-panel design means two PCBs and a ribbon cable; inspect the connection between panels if buying used. For long-term ownership, keep the SD card formatted to FAT32 and avoid removing it during power-up. Despite its complexity, the 112 has proven reliable in most rigs, and its unique workflow makes it a keeper for those who use it heavily. It’s not a module you buy and forget—it’s one that grows with you, revealing new tricks over time.
