Hiho, I've only worked with the python2 version, but I may have an idea where things go wrong.

It may be that the program you are using to send is using the IP-address connected to one of your physical interfaces as a targer, rather than the loopback (localhost) address. In a sense this difference allows you to make your program more secure, by ignoring messages coming from outside of the machine, but unfortunately, not all other OSC-enabled programs allow you control over how they send the messages. sincerely, Marije _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
