I don't have windows 8 so at the moment there is no support for it.
Does Plogue work with windows 8?
Assuming it does:
1) Install the 32 bit version of Plogue (even if you have a 64 bit OS)
2) Go to the folder Plogue\Bidule folder and see if there is a "plugins" folder. If not, make one.
3) Drag everything in the "plugins" folder in the Spec install directory into the above "plugins" folder.
4) Drag everything in the "layouts" folder in the Spec install directory into the Plogue\Bidule\layouts folder.
5) Go to
http://www.plogue.com/bidule/latest/ and get this "Standalone discrete processing test version(version 0.9726)" and put it (the "p2 exe") and put it in the Plogue\Bidule folder. Make a shortcut, call it "P2", and put it on your desktop (is there a desk top?)
Other than setting some Plogue preferences, that should do it.
