ADDAC System 111B (2010s)
A small black panel that adds a hidden control to one of Eurorack's more expressive sample players.
Overview
The ADDAC111 Ultra .WAV Player is a full-featured stereo sampler with granular control, looping and CV manipulation, all in a 3U module. The 111B Expansion makes it a lot more playable. It doesn't add sound. It adds access. It gives you instant trigger-based recall of the first eight samples (labeled A through H) stored on the SD card. No menu diving, no encoder twisting. Patch a clock, a sequencer or a drum hit into one of the eight trigger inputs and that sample fires.
The priority is strict: if two triggers hit at once, the top one wins. That's a design choice, not a bug. The 111B assumes you're building a performance rig, so you can jump between vocal snippets, glitch hits or rhythmic loops with the reliability of a drum machine. No latency, no buffering, no CPU hiccups. The module itself is dead simple - eight inputs, no knobs, no lights.

Key Features
Instant Sample Access Without a Screen
Even compact synths now ship with OLED displays and multi-level menus. The 111B goes the other way. It assumes you've already loaded your samples onto the SD card - A through H in the root directory - and skips the GUI entirely. No scrolling, no selecting, no patch interruptions. The module reads the file names and maps them statically. Once it's set up, there's no file management mid-performance. Sample playback becomes a patchable event, like hitting a snare or flipping a switch.
Priority-Based Trigger Logic
When two triggers arrive at once, the 111B doesn't try to play both. It picks one. The topmost input (A) has priority, then B, and so on down to H. In live use, that keeps overlapping samples from turning to mush and gives you clean transitions or deliberate cut-offs. You can stack triggers from different sequencers, assign them ranks, and use the priority order to build call-and-response patterns.
Physical Integration with the 111
The 111B isn't a standalone module. It mounts directly behind the ADDAC111 via a ribbon cable and shares power and data through that connection. Once installed, there's no extra power draw to worry about, no MIDI and no firmware updates. The tight coupling means no dropped notes and no sync drift. It also means you can't use it without the 111.
Historical Context
The ADDAC111 emerged in the early 2010s, when Eurorack was shifting from purely analog sound generation to hybrid systems that embraced digital flexibility. At the time, sample playback in modular was either clunky (via external gear) or overly complex (with deep menu diving). The 111 changed that by offering intuitive, voltage-controlled sample manipulation in a compact format. But it still required manual selection, which is fine for studio work and less so for live sets. The 111B answered that need, arriving as a natural evolution rather than a reinvention. It reflected a broader trend in modular design: performance-oriented expansions that prioritized immediacy over configurability. While other brands chased multi-functionality, ADDAC focused on making a single action, sample triggering, bulletproof.
Collectibility & Value
The 111B is a companion piece, so it rarely trades alone. Most listings are bundled with the ADDAC111, and standalone units are uncommon. When they do appear, prices range from €80 to €150 depending on condition and region. The module has no moving parts or displays, so failure points are minimal. The main risk is physical damage to the ribbon connector or bent pins during installation. Owners report that once mounted, the 111B is essentially maintenance-free. Sourcing one today takes patience. ADDAC's legacy modules are no longer in production, and while not rare, they're not being reissued. If you own an 111 and perform live, the expansion is useful. For collectors, it's a footnote. Condition matters less than completeness: a missing ribbon cable or mounting hardware can make integration a hassle. Verify that the module ships with the necessary internal connector before buying.
