In Raw Panel mode the controller will work as a TCP Client connecting to a server IP address on port 9923.
The server receives simple action commands when buttons, encoders, faders etc are activated.
In return the server sends button colors and display content.
The API is documented as “UniSketch TCP Client” on our GitHub repository.
In Raw Panel mode, all the logic is placed on the server, which is typically a custom written software application.
