Please tell me if I'm right or wrong.

I have a few cases with modules:

Case 1: standard basic system 2 with 2 x VCO 110 and A-190
Case 2: another case with 3 x VCO 111 plus A-141 VCADSR.

In order to control Case 2 with the same gate and CV from the A-190 I only need an A-185-1 in Case 2.
When I connect The A-190 to  the A-185-1 it should be allright, right

I read the A-185-1 manual but why should I also put an A-185-1 in Case 1
