I am currently running Cubase VST 5.1 on my DAW. It does everything I need and runs all the tracks with effects and plugs I can use but is beginning to have some compatibility issues in terms of being able to interface with newer products like control surfaces being released. I record to 24/44.1 at the moment and I don't feel a compelling need to increase the sample or bit rates and I am very happy with the tools provided in Cubase VST 5.1. I find the stock plugs do pretty much all that I need and I haven't found any reason to go out and purchase any cards like the UAD or the TC Electronics. So the question is is there any reason I should consider an upgrade to SX 2.0 or should I just keep beating this horse until it dies?
