I have owned the PreSonus AudioBox USB for a couple of months now. I've been successfully stumbling along and have managed to achieve a few of my short-term goals: practicing and recording bass cover tracks over iTunes songs, mostly. The box says the interface comes "with ... Steinberg's Cubase LE 4 48-track recording and production software giving you everything you need to get started recording and producing your music." Here are my questions. Where is Cubase? How do I find it and open it up? Why would I want it when I've begun using their free Studio One 2 Artist DAW?
