A recurring source of confusion when receiving OSC with LiveGrabber is that some OSC libraries or apps format their OSC arguments as strings instead of floats. This will cause LiveGrabber to ignore their messages.
A quick way to check if your message arguments are formatted correctly is to send them to OSCulator.
As an example, I’m sending messages from Max (patch below) both to LiveGrabber and to OSCulator, first with float arguments and then with string arguments.
In GrabberReceiver, there is no visual distinction:
But in OSCulator, there is:
As you can see, the messages formatted as strings are displayed as such.
These string-formatted arguments will not work with LiveGrabber. They will be displayed as being received in GrabberReceiver, but any receiving devices such as ParamGrabber will not show a blinking input indicator and nothing in Live will be controlled.
If you own Max, you can repeat this test with the Max patch I used:
