Ciao the question is how to let Cobalt comunicate with QLab software or similar...thank you.

that communication could be made by OSC. what do you want to remote control? run a cue on cobalt and have qlab react? or the other way round?

I would like to run a cue in Qlab to fire the main playback in the Cobalt

We found the solution between Cobalt and QLab with Osc: in QLab preferencies we need to set OSC port port and adress and in the workingspace set the output network port.
