ADDAC 112 Looper Granulator (2021–)

A dual-mono looper and granular processor that turns audio into shimmering, splintered galaxies—with a screen that shows every crack and flicker.

Overview

You press record and your synth drone gets sucked into a black hole, stretched into a five-minute buffer, then chopped into microscopic grains that scatter like shrapnel across the stereo field. The ADDAC 112 doesn’t just process sound—it dissects it, lets you poke around in the open cavity, and then reassembles it with surgical precision. This isn’t a module for casual looping; it’s a full forensic audio lab squeezed into 45HP of Eurorack real estate. When you first patch in a clean oscillator tone and then twist the grain density up, watching the OLED screen bloom with thousands of tiny waveform fragments, it feels like peering into the DNA of sound itself. The interface is dense, yes—knobs for grain position, size, pitch, randomness, envelope, and deviation crowd the panel like control surfaces on a spacecraft—but once you learn its language, it becomes one of the most expressive granular tools in modular synthesis.

Unlike many granular modules that obscure their inner workings behind minimal interfaces or cryptic menus, the 112 wears its complexity proudly. It combines a full-featured looper engine with a deep granular processor, letting you record audio, manipulate it in real time, and then feed it into a granularizer with voltage control over nearly every parameter. The looper can overdub, switch between multiple loops, and sync to external clocks, while the granular engine slices the buffer into grains with adjustable timing, pitch, and spatial placement. You’re not just triggering grains—you’re sculpting them, nudging their start points, stretching their durations, and scattering them across time with CV-controlled randomness. The screen, a rare luxury in modular gear, gives immediate visual feedback: you see the loop waveform, the grain cloud, and how your adjustments affect both in real time. It’s like having a sonogram of your audio, letting you fine-tune the chaos with pixel-level accuracy.

And make no mistake—there’s chaos here. At high grain counts or with aggressive modulation, the 112 can stutter, freeze, or crash entirely, especially under heavy CV load. Firmware updates have improved stability, but owners report occasional lockups that require a reboot. This isn’t a flaw you can ignore; it’s a trade-off baked into the design. The module pushes a relatively modest CPU to its limits, and while the sound quality remains pristine at 16-bit/44.1kHz, the processing overhead means you’ll need to manage expectations during live performance. That said, many users treat the instability as part of the character—glitches become textures, crashes become transitions. Still, if you’re looking for a bulletproof, set-and-forget granular module, this isn’t it. The 112 demands attention, patience, and a willingness to dive into its firmware quirks. But for those willing to wrestle with it, the rewards are immense: a level of control and sonic depth unmatched by most of its peers.

Key Features

The Dual Engine: Looper Meets Granular

The 112 doesn’t just pair a looper and granular processor—it fuses them into a single, interdependent system. The looper isn’t an afterthought; it’s the foundation. You record audio into one of several onboard buffers, pitch-shift it, overdub layers, and switch between loops—all while feeding the same material into the granular engine. This tight integration means every edit to the loop instantly affects the grain source. Want to granularize a guitar phrase you just recorded? Done. Want to pitch it down an octave first? The grains follow. The module even includes a suite of preloaded samples on the SD card—an Amen break, noise sweeps, ambient pads—that let you start experimenting immediately without patching in external sources. But the real power lies in using the looper as a live sampler: capture an oscillator sweep, freeze it, then spend the next ten minutes dissecting it into microtonal shards. The ability to save and recall loops means you can build a library of textures, then reprocess them in new ways across different patches.

Voltage Control Without Compromise

Every major parameter on the 112 has a corresponding CV input, and most include attenuverters for precise modulation shaping. You can voltage-control grain count, size, position, pitch, randomness, and even the deviation of those parameters—meaning you can modulate how much randomness varies over time. This level of control is rare in granular modules, where many limit CV access to just a few core functions. Here, you can patch in an LFO to slowly expand grain size while a sequencer jumps the playback position, all while an envelope modulates the dry/wet mix for dramatic swells. The patch bay is thoughtfully laid out, with inputs grouped by function and color-coded for clarity. But be warned: the module outputs hot signals, especially in granular mode, so running it into a mixer or effects often requires external attenuation. It’s not a flaw, just a consequence of its high headroom design—this thing was built to handle extreme processing without clipping, but that means you’ll need to manage levels downstream.

Visual Feedback That Matters

In a world of blind modulation and abstract control, the 112’s OLED screen is a revelation. It doesn’t just show menu text—it displays the actual waveform of your loop, marks the current grain positions, and animates how changes in density or randomness affect the grain cloud. When you scrub the grain start point, you see the playback head move across the buffer. When you increase grain size, you watch the individual slices grow longer. This isn’t eye candy; it’s functional feedback that lets you make informed decisions. You can see when grains overlap, when gaps appear, or when the buffer is nearing overflow. The screen also includes a zoomed loop editor for precise start/end point adjustment, which users report as invaluable for tight rhythmic editing. While some purists might argue that visual feedback breaks the “modular ethos” of tactile exploration, in practice, it makes the 112 far more intuitive than modules that force you to guess at what’s happening under the hood.

Historical Context

The ADDAC 112 arrived in 2021 at a time when granular synthesis in Eurorack was no longer a novelty but a mature field. Modules like Mutable Instruments’ Beads, Qu-Bit’s Nebulae, and Make Noise’s Morphagene had already defined what was possible in compact, affordable formats. The 112 didn’t try to beat them on size or price—it aimed to surpass them in depth and control. Where Beads offered elegance and immediacy, the 112 offered granularity (pun intended) and transparency. Where Nebulae leaned into dark, textural mangling, the 112 stayed pristine, letting the source material shine through. And while Morphagene embraced a more abstract, sample-manipulation approach, the 112 doubled down on real-time performance and visual feedback. It was a bold statement from ADDAC, a Portuguese company known for quirky, design-forward modules, that they could compete at the high end of Eurorack’s most complex category.

The module also reflected a broader trend in modular synthesis: the growing appetite for “supermodules” that combine multiple functions into a single, powerful unit. At 45HP and nearly 700mA draw, the 112 is a power-hungry beast, but it replaces what might otherwise take three or four modules—a looper, a granular processor, and a sample player. It’s the kind of investment that only makes sense in a mature system, where the user has already explored the basics and is ready to dive into advanced sound design. Competitors like Instruo’s Arbhar or Mungo’s Hauler offered alternative takes on granular processing, but none matched the 112’s combination of hands-on control, visual feedback, and integrated looping. It wasn’t trying to be the easiest granular module—it was trying to be the most capable.

Collectibility & Value

The ADDAC 112 isn’t a vintage classic in the traditional sense—it’s too new, too tied to modern firmware and digital processing—but it’s already carved out a niche among collectors of high-end Eurorack modules. Its original price of $699 placed it firmly in the premium tier, and while it occasionally appears used for around $550–$600, it rarely drops below that range. Condition matters: units with clean screens, responsive buttons, and no firmware corruption hold value better. The module’s complexity means that repairs aren’t trivial; a failed SD card reader or corrupted firmware can render it unusable without access to ADDAC’s support team. Owners report that crashes, while less frequent with updated firmware, still occur under heavy load, and a hard reboot (power cycling) is often the only fix. This makes reliability a real concern for live performers, though many treat it as a studio centerpiece instead.

What to check before buying? First, verify the firmware version—anything before 1.4.3 is likely unstable. Second, test all buttons and knobs for responsiveness, especially the loop and grain selectors. Third, check the screen for dead pixels or flickering, which could indicate a failing display driver. Fourth, confirm the SD card slot works by loading a sample. And finally, listen for audio glitches during high-grain playback—crackles, dropouts, or freezes under load are red flags. The module’s size and power draw also mean it’s not for every system; you’ll need a case with ample space and a robust power supply. But if you’re building a high-end modular rig focused on experimental sound design, the 112 remains a compelling, if demanding, centerpiece. It’s not the kind of module you buy on impulse; it’s the one you save for, research, and then spend months unraveling.
