hi,
i was trying out my rather old osc client object for mxj with pd's pdj. which wasn't working, and hence led to a new polished version that works fine in pdj:
http://github.com/Sciss/PDOSCClient
there is a compiled binary also in the downloads section. please see the README.textile for installation infos.
why? in order to have bidirectional OSC communication from one object, that is sending and receiving is done from the same socket (port). this is required for instance to talk to SuperCollider as there is no way to receive client notifications with disparate [sendOSC] and [dumpOSC] objects.
have fun! best, -sciss-
