Analogue systems

The Doepfer power connector has 16 pins - 2 of them belong to the
CV-bus on the power distributing board. If ASys follows Dopefer's pin
out with their RS15 power sockets this would explain how a CV can
spread without a patchcord. Mind you, it's still strange since you
actually should have to connect a CV to one of the 4 VCOs to controll
all of them via the CV-bus...

BTW On the Doepfer bus boards are jumpers to (dis-)connect the CV bus.
