No. From the client perspective, ports have a single buffer associated with them, so that clients deal with a simple, pure, sweet and lovable world. Any mixing that is done has to be handled either before the client is called, or in a function that the client calls, such as audioengine_port_get_buffer(). If this is what you mean by "the client does the mixing", then we're fine. But I don't want to expose the notion of a "connection count" to the client. --p
