Is it ok to have 2 instances of OSC/PAR with the same port in one Ableton project?
Or better use 2 ports?>
or even 2 ports is not a good Idea?
All cases should be fine. The port that you are selecting is the port on the receiving machine, not the local port on your sending machine. Since OSC uses UDP to send it’s data, it’s ‘connectionless’. which means multiple sources can send data to the listening port and it’ll just read the data as it comes in from anywhere.
