I bought Notion and was going to buy Sphere. Now, it seems Notion, as well as Studio One (which I almost bought outright) are included in Sphere. Am I correct that I didn't need to buy Notion if I was going to get Sphere? And, will the company give me a refund; I haven't opened the program yet, but did install it. BTY, I purchased it from MusiciansFriend, not PreSonus. Thank you!
