Hi, I wouldn't know how to configure pd to not do this, however a dirty
hack could be to use aj-snapshot to restore connections; you'd call it
as last line of your script (maybe preeceded by a "sleep 3" to wait
for all applications to have properly started) with the option (I don't
remember which) to make it first disconnect all connections - i.e. it
first disconnects everything, then makes only the connections you say
him so (by passing him a file).

aj-snapshot is really neat and manages jack audio, midi and alsa midi
