A4 MK2 CV -> Mother 32: cables connection

Hi again!
I’ve finally got some time to try these connections out, but no sound comes out of the A4. Wondering what am I missing !!?
CV A and CV B are connected as in the chapter 15 of the manual. Didn’t connect CV C to filter, but that should be the problem.
I don’t think I have to connect the output of the M32 to the external input of the A4? If I_ do that I have a different kind of connection

All the CV configuration seems to be ok.
I’ve just followed these instructions, the only different. thingy is the Note 1 is set to C2. That’s it

Why I can’t get any sound out of it??! Any ideas anyone?
