Hello Zoƫ,
> If I understand correctly, it's fine to override the bus by plugging something into the *front* of a module to give it another gate or CV signal to pay attention to.
basically you are right, but some early modules (don't ask me which
ones) did not use the switching function of the sockets. You had to
decide with an jumber on the pcb, whether you want to use the socket
input. Unfortunately if you enable the socket, then the signal is fed
into the bus too.
Dieter might jump in here. As he should have the overview.
