Creating bus sends ?

Hello I love using Mixbus which runs on ardour because of the easy Mixbus I can easily send tracks to. But on ardour how do I send tracks to a bus I’m not sure how ti send tracks I want to a created track or bus or whatever ardour calls it

Assuming you have some Busses in the session, the context menu of the processor-box will have a “new send” entry: http://manual.ardour.org/signal-routing/aux-sends/
