Upgrade to Cubase 5! Dai just bought it and the mastering suite is fantastic!
Yeah, I understand it includes things like side chain compression that mine (version 4) doesn't...however, it's not the gear, it's me who's the problem! It was the same during my first musical phase, when it was all analogue. For me, mixing has always been slow, painful, then a chore, then I can't tell what's what and it all blurs together. It's the woolly bits that accompany the bass/kick that is my main undoing, like the submerged bits of icebergs scraping together....a proper producer, who can hear these things and know what to do about them, is a boon. If you can afford them. Which I can't. And a proper mastering engineer, ditto. Still, the show must go on...although I won't put wet towels on the cymbals or have the drums sounding like cardboard to get round it. Maybe I should!
