ADDAC111B Ultra .WAV Player Expansion (–)
Want instant, trigger-based access to your first eight samples without menu diving? This is the silent partner your Ultra .WAV Player was missing.
Overview
The ADDAC111B Ultra .WAV Player Expansion isn’t a standalone hero—it’s the quiet utility player that transforms how you interact with the ADDAC111 Ultra .WAV Player. Made by ADDAC System and sold through Analogue Haven, this expansion module exists purely to extend functionality, not replace it. If you’ve ever found yourself scrolling through SD card files mid-performance, you’ll appreciate how this little board cuts straight to the chase: eight dedicated triggers for the first eight samples (labeled A through H), no navigation required.
It slots directly onto the back of the Ultra .WAV Player module—no bus board connection, no extra cables snaking through your rack. That means it doesn’t draw power independently or communicate via MIDI or USB; it’s hardwired, lean, and purpose-built. And while it doesn’t let you play multiple files at once, it does enforce a clear hierarchy: if triggers for B, E, and F all arrive simultaneously, file B takes priority. It’s a small but meaningful design choice that prevents audio chaos when your sequencer gets busy.
This expansion arrived as part of the ecosystem around the ADDAC111 Ultra .WAV Player, which itself was billed as the long-awaited upgrade to the beloved ADDAC101 .WAV Player. That lineage speaks to ADDAC System’s focus on practical, performance-ready sampling in Eurorack—no frills, just reliable playback with hands-on control. The 111B doesn’t reinvent that wheel; it just gives you eight faster spokes.

Key Features
Direct Back-Mount Installation
Unlike most Eurorack modules that plug into the bus board, the ADDAC111B physically attaches to the rear of the Ultra .WAV Player module. There’s no separate connection to the power bus—everything flows through the parent module. This keeps your build clean and avoids cluttering your power supply, but it also means the expansion is entirely dependent on the main unit. No standalone operation, no field upgrades. It’s a fixed pairing, which suits its role as a control expander rather than a full-featured add-on.
Eight Trigger-Accessible Files (A–H)
The core function is simple: assign one sample per trigger input, covering the first eight files on your SD card (A through H). These are hard-mapped—no reordering, no remapping via software. When a trigger hits, the corresponding file plays. This turns your sampler into an instant-access instrument, perfect for live sets where timing matters more than browsing. It’s like having eight dedicated sample pads built into your rack, each with a fixed sound.
Priority-Based Trigger Handling
Concurrency isn’t allowed—only one file plays at a time. But instead of random selection or first-come chaos, the module uses a top-down priority system. If multiple triggers arrive together, the one highest in the list (A being top, H being bottom) wins. So if B, E, and F all trigger at once, B plays. This deterministic behavior is critical for reliable sequencing and eliminates guesswork in complex patches. It’s not flashy, but it’s thoughtful engineering for real-world use.
