First make sure you've installed the original plugins!
Then you can put these devices into your user library, basically anywhere.
Default location of the User Library:
When you install Live for the first time, the User Library is created at this location:
Windows: \Users\[username]\Documents\Ableton\User Library
Mac: Macintosh HD/Users/[username]/Music/Ableton/User Library
Please note that Live has to analise your user library after you put your devices in there... It could take a while.
For the time being, you can just drag and drop these devices on your track from your user library. until Live analyses your folders.
Always use the latest plugin versions of the plugins. ( I will follow every update with the wrappers.)
