OSC-route dynamic setting
I would not use cnmat objects at all, but that is another topic.
Read the OSCroute help file, check
Changing the arguments to OSC-route
where it says :
"You can change the address prefix associated with each outlet with the "set" message:"
well that’s not really another topic, [opensoundcontrol] and [osc-route] objects are kind of deprecated ; you should be able to do what you want with the [route] object, ditching [opensoundcontrol] altogether, and using [combine] to change the adresses if needed.
