I have to say the second method is nice when those times come up when adding CVs is what you want but really is not a good solution for when you don’t want to do that. It means you have to pull the module out to turn it OFF instead of the much simpler act of inserting a jack. I’m a firm user of the CV/Gate bus and almost every cabinet I have has a A-185 Bis Access module in it. I often mix buss use and non buss use in one cabinet and the normalizing really makes this easy. I can see where in the VCO modules that have only one CV input that this is much more useful, but would suggest that the VCOs that have two CV ins, that the normalized signal go to the 1v/oct input (with a jumper) and the variable CV input be made to have a 1v/oct response when the pot is turned fully CW. Then the mixing action could still happen.
