OSC Data Monitor

Monitor incoming OSC (Open Sound Control) data on your network with this Processing application. I also explain in a video how OSC works.

I’ve developed this program so you can quickly check if you have communication with OSC sending equipment in your network. 

Currently there isn’t a signed app for MacOS (and security get’s tighter). You can work around this by making your security settings less tight, but it’s some extra work.

 I’m investigating if it’s worth it to put effort in creating the signed app. Since I’m giving away my software for free below I hope you could answer some questions in return in this TypeForm. Thanks in advance!

Thanks to Andreas Schlegel (sojamo) for the execelent OscP5 and ControlP5 libraries on which this program heavily relies.

  1. I’ve just managed to get touchosc (partially) working on iphone (4s) with logictouch template & reaper (5) daw wirelessly. I was going to fix the template, but when I run the osc-datamonitor I get the no jre message…

    I’ve installed java 8, which fixed the same issue with touchosc…

    Does osc datamonitor require an earlier java?

  2. Hi, OSC monitor are blocking port when lisening it. Other aplication can not receive OSC message in the same time in the same machine. Is it a bug or correct action?

  3. Thanks for that tool. I have it running fine on Mojave.
    However: how do I change the IP address that I want to listen on? I have several OSC-apps running on my computer so I want to listen to my local IP “” but the data monitor just listens on my LAN address.


  4. New to OSC.

    It seems the target software binds to the destination port so I cannot monitor the traffice unless I close down the target software?
