no problems geronimo, thanks for your feedback.
To let OSX to know that something changed within the plug-in folder, you have to close the session and reopen it (or shut down your computer which can be longer).
It is the first time we are working on 64 buts plug-ins, so there are maybe some knowledge we are not aware of !
The major point is that, at this time, I don't know if it is possible, on OSX, to have the both 32bits and 64 bits versions with the same plug-in name (to keep project compatibility). On windows, you just have to install them in two different folders, setting your DAW to choose one or the other folder depending on its version (a 32 bits DAW can't launch a 64 bits plug-in)
On OSX, I really don't know. So if this feature is needed, advices are welcome !
