like he ^^ said

try one of the analog emulators like native instruments pro-53

its a great place to start and offers most of the sounds that you'll need for techno and trance.

z3ta+ is a great synth but there are a lot of routing possibilitiess that can make it seem daunting to a beginner. its far to easy to just come out with generic trance sounds on it if you dont delve into what it can do.
