ADDAC System ADDAC111 Ultra
The ADDAC111 Ultra is the upgrade to ADDAC System's ADDAC101 .WAV player, and people had waited a long time for it. It's a Eurorack module that keeps all the functions of the original and adds dedicated controls and new features. It retailed at $649.00. The companion ADDAC111B expansion module, which allows trigger-based recall of the first eight files for sequencing, retailed at $169.00.
ADDAC chose micro SD cards for this version to keep the hardware construction simple and the module only 3 cm deep. The module is 16 hp wide and draws 150 mA max. It works with both ±12V and ±15V supplies through a standard 8×2 IDC Doepfer-style bus board connector. CV inputs run ±5V. CV outputs run 0 to +10V.
The operating principle is simple. Loop size, start point, and sample rate define how a loop plays. Loop settings determine whether a sample loops or plays once. File access advances to the next or previous file. A VCA section controls overall volume, and an envelope follower generates CV from the audio amplitude pre-VCA.
New features over the ADDAC101 include better loop size and start point control with separate CV attenuators, and bipolar inputs. File selection is now dedicated, with individual skip and a random gate input (all files mapped to 0-5V for sequencing). There is a dedicated loop settings state with external control, and sample rate on/off with external control. Sample rate inputs are bipolar, with 1V/oct sample rate spanning −4 to +1 octaves. A loop points feature works like a DJ CD player's loop function - press once to mark the loop start, press again to mark the end and begin looping, with on/off state and external control.
ADDAC describes the 111 as "a mature .wav player based on what we felt the 101 was missing mixed with a revision of all the feedback we got over the years from all the 101 users." The ADDAC111B expansion plugs into the back of the Ultra, with no bus board connection, and lets you trigger the first eight files (A-H). If multiple triggers arrive simultaneously, priority goes top to bottom.
No production years, audio performance specs, or owner reviews surfaced in the research. The record is thin beyond the manufacturer's own documentation.
