Have you enabled the OSC Receiver from the startup options, and turned off firewalls?
Also please note that the playSet command you are using is not existing.
It should either be playSetId or playSetIndex, please look at the list:
You could also make these calls using the HTTP receiver, for play command it can be simpler/safer
I am trying to send OSC Messages from Processing to Facade but it is not answering. Does it exist a way to know if Facade is receiving the OSC message?
I have modified an example of Processing to test, I put relevant pieces of code below
Is it possible that the trial version does not allow the OSC connection?
