We have purchased Cubase 10 Pro, however we are having problems setting it up to work with midi, we really need a “Setting up Cubase for dummies”.
This is our equipment:

16gb of Ram Installed
64 bit operating system x 64 based processor
Graphic card N.Videa GTX 1070 8gb
Sound Module for midi Roland Super JV-1080

WE HAVE NO SPECIALISED SOUND CARD - is this a problem

Please, if you can help, how do we set this up, from putting leads in right inputs to setting up inside Cubase, as simply as possible, the midi side of things is really important, your help would be appreciated.
