Mind Monitor

I would like to send data in real time through OSC streaming to the program on the PC.
But I am a high school student who doesn't even know much about OSC. (I can't find the information well even if I search for it.)

I'm sorry, but could you tell me more about how to stream OSC to matlab or other programs you've tried on Mind Monitor, including the source code?

I tried opening the file from http://www.MuseMonitor.com/misc/OSCMonitor.zip, but a new window did not open and nothing changed.

Have a look at the FAQ on the website to start:

There are also links there to my GitHub with python code samples.

OSC is a standard streaming protocol that can be used for many things:
