Yes, that is valid only for Doepfer VCOs. For other it depends on the
dedicated "foreign" module.

The outputsockets never beak the connection to the internal bus. They
are simply parallel. So: if you will hava a Braids and a A-110, then the
A-110 will get the CV from the bus, the Braids will get its CV via a
cable from the Interface CV-out to the Braids CV-In. (I have exactly
this combination in my live case, so I know it for sure :-) )

I'd say 99% it is wrong. It might happen, if the MIDI-interfaces gate
out is completely unsecured (direct connection to the CMOS-chip). I
think the very old MCV-1 interface had only a resistor between the uP
chip out and the socket; this could lead to problems with high voltage
gates from old ARP or Roland synths.
But the A-190-1 has a transistor-buffer in the gate-out line. So there
is no danger at all.

For your example: you simply can let the interface send its gate via the
internal bus, while you insert the LFO-"gate" to the Gate-In at the
front of the second ADSR. This will break the connection to the internal
gate bus. There will be no "shorting" with the internal gate.
