If I understand your question correctly - yes, you can do completely random stuff (such as kit pcs, variations of grooves, built in effects, etc) to make your own sound, etc.
If you are new to the software approach - you may be a little overwhelmed. That's ok, though. There are a lot of people on this forum who are more than willing to help you out.
Not to mention - you could always visit us over @ the
ToonTrack forum, too.
There are a lot of guys over there that use Cubase & Nuendo that could help you with a blindfold on their eyes!
Enjoy.
