Hi, I just looked at the downloads section of this site and searched for "Logic Pro MainStage 2" and found it as a normal download. I couldn't try it out because I stilll have to move from 10.5 to 10.6, but I am fairly certain I saw it there-check for yourself.
I just looked again and had to remove the Logic pro from"Logic pro MainStage 2" before the Mainstage update appeared, it seems to give slightly different answers each time, don't we all? And it is only 2.1.3 so 2.2.2 will appear here later, I assume.
Sorry all, I just read the full disscusion and I understand now the 2.1.3 could only become 2.2.2 when $30 was paid for it and I suppose only available in the app store. Apple doesn't worry about software anymore, they want you to buy all their hardware and let them follow you around where ever you go, times change, so do companies[corporations are people too,in the USA.]
