Using MidiHub with other Midi interfaces?

[Giedrius]

It’s possible, some software like your DAW or something else (MIDI Patch Bay was suggested) has to route the MIDI data around. See this topic for related discussion:

USB Controller into midi hub in OSX

I can’t figure out how to route a USB controller into a port on the midihub using Apple’s Audio MIDI Setup. I have an Akai MPK keyboard connected via USB to my computer. I can see it and the four port midihub in the Audio MIDI Setup, but when I try to take the output of the Akai and connect it to a port on the midihub, the virtual cable will not connect. Am I missing something?
