Audio I/O with Cubase 8, Mac Mini and Korg Minilogue

I just picked up the Korg minilogue and I am trying to integrate with the rest of my components and Cubase Elements 8. Cubase recognizes the synth, but my question is how to setup the audio inputs and outputs.

Korg is plugged into the ‘audio in port’ of the mac mini.
Korg is plugged into the computer via USB.
I can record using Cubase, but how can I set it up so that I can hear what I have just recorded from Cubase through the computer AND hear the audio outputted by the minilogue at same time? All through headphones.

Please help. Thank you.
