I just recently purchased a PreSonus AudioBox USB. With it came Studio One 3 Artist. I'm completely new to the audio world, so please bear with me. I noticed that in Studio One 3 Artist, there are three included instruments under "Presence Studio Grand" (Studio Grand, Pop Grand, and Rock Grand).
At the same time, I noticed that PreSonus offers a "Presence XT PreSonus Studio Grand" add-on for a price. My question is, is this add-on the same as the 3 instruments that already come with Studio One 3 Artist? Or are they completely different?
