Right now I'm using Cubasis VST 4.0 that I got with my E-mu 0404 card, which from what I've read is the really really stripped down version of Cubase, even more so than LE. What are the benefits of upgrading to Cubase LE or even SX? I'm looking to record some jazz/rock/electronica, and i play bass, a few horns (trombone, sax) and a little synth as well (i have a hard synth). So what are the benefits of getting a fuller version of Cubase?
