They never wow you with an upgrade price either especially on 32c. The authorization is simple, you don't have to be online. You can install it on every machine you have. As for me I can't really get into this software.
I think it's in My Documents. They don't even give you the option of where to install. You can move the loops but not the loops and instruments folder if you want their Vita instruments to work. There was a rant about that one their forums.
These are just as responsible for the price reductions on the VST market. There people making great free ones and then people start buying their paid versions.
I don't get the phrase libraries. I prefer loops instead. I have some of those Sonokinetec phrase libraries, one trick ponies and the newness wears of quick.
I don't know why they bother with the code and there is no place to enter it. Groove Agent is a nice plugin. I'm finding how annoying dongled stuff can be with you open up a DAW on another system without the dongle and it interrupts a VST scan because there is no licence for Retro or Pad Shop.
The background stiff is nice. Now they have a buy 1 get one free. I also like to cover art. I guess loop libraries are bringing back the cover art.
The Electro Trap library is nice if you don't use any of the melodic stuff.
I bought the Celtic one some time ago and it came with soundfonts. I wonder if those are the full libraries. I do like Flamenco Sounds and used it to make a backing track. I'd give it a pass unless it was under $20.
