How do you even set this up?

[MattJay]

Firstly just have to say the online manual for the C is utter useless with regards to getting this thing wired up

Anyway rant over....

Just got my hands on a virus c and need some help setting it up

this is my setup

focusrite saffire pro 14 audio interface
m-audio oxygen 49 keyboard. note: usb only
virus c

the guy in the shop said i only need 1 midi cable but not sure what jacks i should be putting it into? Then i face the challenge of getting logic to recognise it and play through it!

could anyone explain where the cable needs to go e.g. which ins and outs and if i need to do anything additional with the saffire software as well as logic?
