If you have a several machines in the future, but only need to use a few of them at once or want to redirect outputs from one instrument into another, you could connect all the connections from all the instruments into the patch bay and then just patch the ones you want to send to/from the computer into the (small) audio interface, rather than have all the connections permanently connected to a (large) audio interface.
It’s worth thinking about whether you would work that way in the future. It may not necessarily be the way you want to work.
