This is a legit question; I don't suspect the OP is trying to steal, just understand.
I asked this a few weeks ago and didn't get an answer ,afaik. I got AD2 with X3 and those three kits can be used in other DAWs. I also purchased three more kits.
One of the highlights of the platinum upgrade is three more AD2 kits, but unless they have restricted their use to Sonar, I don't see how they could "take them away" after a month.
If they allowed you to "keep" them on cancelling, you would be able to sign up for a month, cancel, sign up for another month and get three different kits, and repeat until you have all of them.
This is a legit question because if they restrict their use to Sonar, they may not be as useful to someone who uses multiple DAWs.
I'd like to know too.
