cubase vst32 ?
No Cubase SX 2.2 demo?
Cubase SX & Logic are just as good as eachother and can do pretty much the same thing, Cubase is better suited to a PC, Logic is for MAC, Cubase is a better choice if you are on a budget as it goes for a lower price and there are more free VST stuff going on the internet that sound great that wont work in Logic. Also it has more configurations for home set ups with smaller CPUs.
Allot of Pro's go for Logic as its good with MACs that have always rated as so much better than PCs but there are now some fantastic PCs for sale configured for music and some blow MACs away. more people are seeing Cubase SX/Nuendo is very good.
good luck
