ADDAC System ADDAC301B Dual Expression Pedal Attenuator
The ADDAC301B is a passive 4 HP Eurorack module that brings expression pedal control into a modular system. It's a simple utility. Plug any CV or audio source through it and control the amplitude with any standard expression pedal. An invert switch reverses the pedal's action, which is handy when you want a pedal to close a filter or duck a signal instead of opening it.
The documentation trail is thin. No production years, electrical specifications or detailed reviews are recorded. Analogue Haven lists the module at $90, and the same source says the Behringer FCV100 and Moog EP2 are the recommended expression pedals, though any expression pedal with a stereo jack will work. The catch is that Line 6 mono expression pedals need to be hacked to be compatible. A passing mention on Gearspace references the ADDAC301B as a means of converting expression pedal control to CV, which matches its intended role.
