Using blinds as a precision adder?

I want to get an adder to add together v/oct cv and transpose sequences. i read that shades could be used as a a precision adder if the attenuation was all the way up when mixing two channels. does blinds also posses this ability?

I’m using this 2hp module, for transpose duty:

You can transpose 3 different voices with one source

No, Blinds has VCAs in the signal path, and their gain is slightly mismatched and/or temperature-dependent.
