What I've done in the past to remedy a similar situation was to use the [aconnect] object, queried its ports and compared its output to a symbol like [symbol LaunchKey( or something like that. When the comparison went through I stored the number. I did the same for Pd and used those stored numbers to make the connection through [aconnect]. Don't the patch at hand right now, but this is the overall idea.
