Hello... I'm new here =)

I have a Vestax VCI-100 Arcade edition. I love Electronic Dance Music and Really want to learn how to dj on it. I have a Mac book pro, Tractor Scratch pro and music. And I don't know how to make it work, it didn't come with a manual, just usb cord. I read on forum that I have to download a TSI File. But I don't know where to get it. Please Help.
