Hi @sky and welcome to the community!
can you elaborate a bit: what exactly isn’t working? As I see it, you’re grabbing input from VoiceMeeter Input #5, processing it with an EQ and then sending it back to VoiceMeeter In#5. Can you check if you are getting any input level (either the input port meter on the routing page or the meter in the monitor tabs)? Then check downwards in the routing page, if you’re getting levels. Once you have a working audio level at the output port, the Cantabile side of things should be OK; then it’s VoiceMeeter routing.
Note: VoiceMeeter and Cantabile seems to be a somewhat fickle combination - sometimes, you’ll need to re-start Cantabile’s audio engine multiple times to get them to synchronize and have a working audio connection.
