I'm asuming you would like to import some pre-recorded loops in .WAV format. I'll also assume that you have a legit copy of Cubase and you don't understand the manual (it's all nicely explained in the manual). All you have to do is go to File>Import>Audio File. Make sure that your tempo matches the tempo of the loop. Once the loop is on your Audio Track you can copy it as many times as you want, you can also import as many loops as you'd like onto that same audio track for some variety. Play with it for a while and you'll figure it out, it is quite simple......
