There is an easier way. I'm actually surprised that this isn't common knowledge. I HATE that stupid default beep that cubase comes with.:
1st thing, you NEED a drum VSTi. (halion might have a preset that will work, I don't mess with it that much so your on your own if you want to give that a shot).
This one works fine for the purpose of showing you this:

You have to have the above installed or this won't make sense
(NOTE: This doesn't work in cubase LE version 1 and 4 <never used 5> for some reason, I HAVE TRIED IT. In LE you have to setup an instrument track and write in the on/off notes and make your own click. It sucks but it's the way it is):
For essential, studio and 5 though (this method works for versions 4 and 3 as well):
First (essential and studio won't have this many menu options but this item is in all versions of cubase):
Then this window shows up:
Load up drumcore 3 (might be in a different directory, I'm picky where my plugins are located so they are easier to navigate through)
When this screen shows up hit cancel (you don't need a midi track):
The gui for drumcore 3 should pop up, when it does just get rid of it. The default kit that loads is the acoustic kit and the one you probably are going to want. There is also a electronic sounding kit if you want to mess with it.
If you started a new project with no audio or midi tracks your edit window should now look like so:
