Doepfer

Hello group. I have had a Doepfer mini system with the lower 3u occupied with the mini system and upper row with mixed other modules. 

I hadn't been using the system with much midi before but noticed the cv transmits via the bus to the a110 VCOS  in the lower row and the ADSR in the lower row. 

Is this true for the second row in a standard mini system. Or do I have to make a connection. I have no oscillators plugged into the second row but just would like to know my options for the future. 

I know I can always manually patch cvs from the a190 to other 1v per octave oscillators but just curious if another a110 in the second two would behave the same way. 

Thanks. Hope my question was clear.
