You find a detailed explanation of the CV/Gate bus principles on our

The A-143-1 does not pick up the gate signal from the bus.

> Moreover, Doepfer web page doesn't mention the A-190-4, but since

> Important notes:
> The module comes with installed bus jumpers for CV and Gate. One
> has to remove the jumpers if e.g. an A-164, A-190-1, A-190-2,
> A-185-1 or A-185-2 is already connected to the CV and/or gate
> lines of the same bus board!
