Now I am using QJackCtl and I cannot see a way to add virtual channels. If I increase the number of I/Os in ‘advanced’ to beyond the 2i/2o of my interface, the jack server fails to start. For a recording workflow I use it would be very handy to have the JackRouter device present more I/Os than 2. Am I missing something?
