LOL! I am also easily confused, so I'm sorry I passed it on to you. For some reason, when I went through custom shop, it listed a few things that didn't have a check mark. I had Total Studio Max 2 that came with Amplitude 4 Max, I believe. So I got the crossgrade to Amplitude 5. The unchecked items say they are available in Amplitude 5, Amplitude 5 SE, Amplitude 5 Max or other bundles of which I have the base products but not the bundles (Fender 1 and Fender 2 separately, not the Fender bundle.
Okay, so I just opened Amplitude 5, and they are available in it. I have no idea why they aren't checked off if I already have them. It is frustrating that the various trackers give you mixed info. All that said, I still don't understand why I can't select Amplitude SE or even MixBox (which I already own) but can select Orange, Slash and SVX2, which I also already own or selected.
I guess I'll just pick whatever. Because what else is there to do.....
