It seems like "Florian's" kit was really Julian Bayle's (http://julienbayle.net/). I presume this kit is the decompiled scripts that Julian still offers on his site.

On a side note: I could not get them to work (deleting the .pvc file and replacing it with the .pv file and letting ableton compile them)

I read somewhere this may have to do with ableton running it's own python 2.5 with the current version of pythong being later.

Anyone else have this problem?
