ADDAC111B Ultra .WAV Player Expansion (–)
The first eight samples on your Ultra .WAV Player, each with its own trigger input and no menu diving.
Overview
The ADDAC111B Ultra .WAV Player Expansion is not a standalone module. It is a utility board for the ADDAC111 Ultra .WAV Player. ADDAC System makes it, and Analogue Haven sells it. It extends the main module and does not replace it. It gives you eight dedicated triggers for the first eight samples, labeled A through H, so you don't have to scroll through SD card files mid-performance.
It slots directly onto the back of the Ultra .WAV Player module. There is no bus board connection and there are no extra cables. It doesn't draw power on its own, and it doesn't talk MIDI or USB. It is hardwired and does one job. It can't play multiple files at once, and it has a clear priority rule: if triggers for B, E, and F all arrive at the same time, file B wins.
This expansion came out 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. ADDAC System's focus there is practical, performance-ready sampling in Eurorack. The 111B adds eight trigger inputs to that and changes nothing else.

Key Features
Direct Back-Mount Installation
Most Eurorack modules plug into the bus board. The ADDAC111B instead attaches physically to the rear of the Ultra .WAV Player module. It has no separate connection to the power bus, and everything runs through the parent module. That keeps the build clean and leaves your power supply alone. It also means the expansion depends entirely on the main unit. There is no standalone operation and no field upgrade. It is a fixed pairing.
Eight Trigger-Accessible Files (A–H)
The core function is simple. Each trigger input gets one sample, covering the first eight files on your SD card (A through H). The mapping is fixed, with no reordering and no remapping in software. When a trigger hits, the matching file plays. That makes the sampler an instant-access instrument for live sets, with eight sample pads' worth of fixed sounds built into the rack.
Priority-Based Trigger Handling
Only one file plays at a time. When several triggers arrive together, the module uses a top-down priority system. The one highest in the list wins, with A at the top and H at the bottom. So if B, E, and F all trigger at once, B plays. The behavior is deterministic, which takes the guesswork out of complex patches and sequences.
