I changed Make OSC Output -node to Make OSC IP Output -node, to send only to localhost (127.0.0.1). Now OSC messages are sent only once.
Help of Make OSC Output -node says that it sends messages to all devices. I made List OSC Devices -node to see what are those all devices, at least for me Vuo shows two devices when only my VuoOscOutBug3.vuo composition is running.
Vuo OSC Clientreceiving from 192.168.56.1 port 4444 Vuo OSC Clientreceiving from 172.16.130.216 port 4444
Is this because of some loop in my network, maybe? Anyway I'm now happy that I can use Make OSC IP Output -node with localhost to solve my problem and send only single messages
Very interesting...thanks for testing this.
I made now a new version of my test composition to have also Receive OSC Message and Display Console Window. If I reboot my machine and run only this application I get same result (every message 3 times). Maybe some part of my network is echoing traffic in general (not OSC related thing?). ...so I tested to turn of wifi, voila, now I get messages echoed only twice (so some improvement).
I will test this with different machines and let you know if I find something. Thanks, you helped me forward with this one.
