dynamic object creation is not yet officially supported and probably
therefore not well documented. 

the only way to know the number id of each object is by implementing a
reference counter yourself, that counts up by one each time you create
an object. however, this will get quite tricky as soon as you start to
remove objects, because then need to keep track, _which_ object you
removed. 

personally, i recommend to not bother with 'connect' messages at all,
but to use [send]s and [receive]s (and their tilde counterparts) in your
dynamically created abstractions. it makes dynamic creation much more
feasible and labelling stays consistent, even when removing objects.

afaik, there is a section called pd-msg-05 somewhere in the help browser
of pd-extended, that has a list and examples of messages to pd and
canvasses.
