in the rack just add enough skjack panels as I /O you want
I m not sure how to configure the stack of the I/O in mac ,if it like in windows editing a tex file or if like in Linux t directly from renoise
you need software that support Jack runing in your pc or the the network (like Ingen , Carla , Sunvox, puredata , reaper , bitwig or multiple rack instances ) Jack can handle Midi, audio, CV and transport
LADISH are very nice to save sessions like Mainstage in mac
