So
1- create a desktop shortcut as usual
2- change the ''cible'' (i'm French so it may differ for you)
put in that field
C:\Users\nlb\Downloads\open-stage-control-1.13.2-win32-x64\open-stage-control-1.13.2-win32-x64\open-stage-control.exe -- --load C:\Users\nlb\Desktop\exampleSession.json --port 8080
You have to customize the path to your situation. Mind the -- before adding the options.
Here i load the exampleSession.json stored on the Desktop and set the port option to 8080 (https://127.0.0.1:8080 to reach the interface)
The available options are described in Server configuration - Open Stage Control (ammd.net)
tell me if it's ok for you !
