Precision adder and active multiple

A 3-input precision adder is combined with a 3-output precision multiple. The multiple input is normalized to the adder output, so you can have 4 adder outputs total.

Very low gain and offset error make this a perfect tool for adding pitch CVs, but it is also a great general purpose tool.

You can multiply an input by 2 or 3 by patching outputs to inputs
