Yes it does. I am connecting both midi and audio through my Project Mix audio interface. All my other DAWs can see the Korg i.e Cubase 7.5,Ableton Live etc, but not Logic Pro x.May try connecting via usb to midi and find some new drivers from Korg.co.uk Will keep you posted.
I think i had to get into the global settings on korg M3 from memory.
Try the karma forums otherwise I will get back to you tomorrow when I get home & look through my notes.
It took me a while to hook it up as well
