I havent used Cubase for a while, but the fact you're using the Vst version interests me... are you using it as a plugin, or am I thinking of another program that go 'vsti' mode? Just cause it might be part of your problem. If you bought Cubase, you should have lots of cool samples to make your trancey beats with. If you downloaded it, there's a good chance it wont come with diddly squat, so you might have to go
http://www.loops.net and find some beats of your own.
