Hi Hans,

This is a great addition to pd! I'm having a little trouble getting it
to work properly, though. When I drag the filter window I get the
error message 'invalid command name "pdsend" '.

I just built it and copied the external binary into my pd path, then
opened the help patch.

thanks,
Spencer
