Warna is a very useful utility module that helps you to manage control voltages in the system. Crammed in just 6 hp, there are five normalled sections: two buffered mults, two inverters, and a summing mixer. Each multiple routes the input signal to separated outputs without loss in voltage. Warna is designed for unity gain - if you apply a specific voltage to any input, it remains the same on the respective outputs. Inverters are hardwired to mults and invert the polarity of the signal applied to them. Both mults are also normalled to the mixer section via inputs. Patching anything to these inputs breaks the normalization.

The top and the bottom section both are buffered 1-in-4 multiples. The input can be inverted with a switch, i.e. its polarity will be changed by 180 degrees. Four inverted copies are then available at the outputs, meaning you can use these two sections as inverter. Bi-polar LEDs display whether the signal is positive or negative: yellow = negative, red = positive. The centre section is a four-input summing stage with amplification factor 1, a so-called unity-gain mixer. The multiples are normalized to the mixer which can be deactivated by patching.
