[PD] inlets, outlets, and dynamic patching

[Matt Barber]

Hello,

Is it possible to send messages to (or within) a particular instance
of an abstraction, in order to dynamically change the number of inlets
and outlets, e.g.?  If so, where do you send the message?  If you send
it to the name of the abstraction patch, it seems to change all
instances.  As an example, imagine implementing something like [gate]
as an abstraction.

Thanks again,

Matt
