When you are making your socket to receive OSC you should probably set
the format argument to binary. when you receive on this socket you will
get an array of byte values which i think would be much easier for you
to parse. I have a working version of some code to send OSC messages
but unfortunately have gotten sidetrack into something else and haven't
completer writing all the code to parse the received OSC messages. I
will send you the code that I have as it may at least give you some
