i 've found many uses with Usine..
1: only one computer , several midi controllers , route via some of copperlan virtual cable , if you want to add a new controller you forget to plug for example , you plug your midi device , it's appear in copperlan and you can route it directly without restart Usine
Settings window :
2: local network of some computers : your midi controllers can be use with all of them without plug/un-plug them each time :
here an example with my bcr 2000 , route to 2 of my computers ( here named musik1 and yan-fixe)
Connections :
also useful with touchscreen as midi remote ..
