Thank you for your reply PILOU.
I downloaded the NodeEditor directly from [http://moi.maxsm.net/nodeeditor/].
Downdoaded an extensions.zip file which had in it the “curves2” and "SubDiv" and others.
Unzipped this file into [C:\...\AppData\Roaming\Moi\nodeeditor\nodes\extensions]
But I do not know how to access these functions (I am using moi V4beta)
