when it comes to pro audio software everyone has their own preferance. dont let opinions make your decision for you. theres a ton of demos and lite versions available for every sequencer. try them all and decide what suits your workflow.

personally i prefer cubase for midi and pro-tools for audio.. but the next person will proably tell you something completly differant :-)

just remember that you can only get out of it what you're prepared to put into it.
