It isn’t obvious (unless you read the manual), but VCV “Mutes” does it.
For any input that has, say, SignalA patched into it, the SignalA is normaled to that one’s adjacent OUT and to all the OUTs below it.
If you then patch “SignalB” to an IN below it (could be several jacks below), that one’s OUT and all below it will have SignalB normaled to them, but won’t affect the OUTs between the A and B signals.
Switching off any MUTE button (turn it from green to grey) only mutes the adjacent OUT jack. It does not interrupt the lower OUTs normaled to it.
