Hi,

The clone is really great ! I think there is a bug, the two first copies seem to have the instance number 0. And if the first inlet in the abstraction is a signal inlet, you can't use it to pass message to the object (like vis). I think this is because the clone uses the flag "CLASS_NOINLET" but perhaps that even if the abstraction doesn't have any inlet, the clone object could have a minimum of 1 inlet (just to use the visible message).  

Anyway thanks !
