Hi, there are some people who have decoded how muse streams data and how to succesfully pair it with a PC.
Here are some links, you can explore it yourself:

They both work with the muse 2016 headband. I don’t think either of them use OSC, but once you get the data into your PC it’s easy to stream it with OSC.
