Hi @andars,
I am really sympathising with your last post. I sometimes also just need a break. Technology can be very frustrating and tiring - sometimes… then again joyful bliss about things that finally work …
You are writing, that you can receive OSC in SP but you can’t send OSC messages, right? Did you try to compile the erlang files? Just a shot in the dark but the symptoms described in this thread match your description.
