[PD] [instance] and dynamic object creation

Yeah, that's because you loadbang all [instance] objects everytime. I think,
for non-standard Pd versions you may be able to use [initbang] inside of
[instance], but actually I would probably use a totally different approach not
involving [instance] at all: When you create objects dynamically, you already
*know* what has been created. So if you want to keep track of object IDs, just
add a counter and pass them as an argument.

Attached is an example containing a subpatch I use very often.

Ciao
