Thanx guy for the help... I have seen a video of a guy who do exactly what i'm searching for, but I am fairly new about the concept of osc, python etc.. I will have to do my Max6 work and learn more about those stuff... If somebody can help me, that will be very appreciated. Because right know, I understand that Blender can receive osc message and Max6 can send it but how the data get transform in a way that you can move object in Blender......
I regularly use Max to talk to my python composition environment (music21).
They key is a python package called pyOSC http://gitorious.org/pyosc
Once installed you can create an OSC server from python.
This would also work in Blender because it supports python. You will
need to do some research on executing python scripts in Blender.
But I don't see why you would not be able to pass data between them.
