I'm a DJ and I made a few demo's using cubase se 3 but then upgraded my computer and got vista so I had to upgrade to Essential 4. I also recently bought wavelab 6 for the crossgrade price so I got a good deal on it but I'm not made of money so I'm just wondering If I really need wavelab. I havent recieved it yet its still in the mail so I'm just trying to see if I can do everything in Essential 4 or do I need Wavlab too.
