We have already begun to introduce this suggestion into new modules.
If you look at the polarizing mixer A-138c you will find a 10 pin header
with the normalizing contacts available at the 10 pin header. A female
connector with 10 pin ribbon cable can be used to connect the normalizing
contacts to other CV or audio sources.

btw. how about a matrix polarizer instead of mixer
