Motivation
This is a useful and often needed utility module. The input voltage is precisely reproduced on the outputs. It comes in handy when you need to distribute signals which must be decoupled. The input signal is buffered and decoupled with means of individual operational amplifiers. One input drives 6 individual outputs. The accuracy depends on the used operational amplifier. For pitch CV I recommend precision OpAmps like the LT1014 (quad) and LT1013 (dual).
