I currently use Cubase and plan to upgrade to Cubase SX. I follow many other forums on computer recording and many are biased to a certain software. I understand the differences with plugins,CPU usaged and the sound card being used. But lets say you were going to plug your guitar into the same or similar sound card and record into any of the known recording software:Cubase, Pro Tools, Logic, Sonar. Would you notice a difference in sound quality? Keep in mind that there's no plugins or anything being added...Just straight guitar, mic, keyboard or whatever you'd want to record. Could you notice the difference????????
