well, nexus sounds pretty well, thatīs right. but itīs not a synthesizer, itīs a rompler what means that the basic sounds are predefined and you have to pay (a lot) for new sound banks cause you canīt create new ones on your own.
i personally donīt like this instant action machine, itīs one true reason why every trance track sounds nearly the same and why people stop to learn how to use a real synthesizer. ever tried out a rob papen synth?
