The 2CVADD-HQ is a dual precision adder especially for adding 1V/octave (pitch-controlling) CVs. This makes it possible e.g. to transpose a sequence. Compared to general purpose CV mixers (like POLAMIX), this module does the summing of the CVs very precise (within a few millivolts), so the desired pitch is not affected.
The module offers three CV inputs for each of the both units; the first unit has an additional fourth input where the CV is subtracted - meaning "transposition downwards".
