/ Examples / OSC / OSC In

This trivial example shows how to open a connection to Hz's builtin OSC server and wait for OSC traffic to be delivered. Here, we expect OSC traffic to originate from an external source (which could be a separate instance of Hz running on your LAN). Here we simply print out the OSC traffic which is a great way to learn about OSC or to better understand behavior of your OSC provider.

For more on Hz's OSC support including a discussion on hostnames and port numbers, see here.

oscin.js

let oin = new OSCIn(); 
let err = await oin.Connect(); // listen on default port (22000)
if(!err)
{
    console.info("oin connected");
    for(let i=0;i<30;i++)
    {
        let msg = await oin.Recv();
        // msg.addr contains the target address, eg "/foo/note"
        // msg.types describes the datatype associated with  elements 
        //    in msg.data[]. "if": means the first element is an integer 
        //    and the second is a float.
        // msg.data is a mixed-type array of elements.
        console.log(`${i} OSC msg: ` + JSON.stringify(msg));
    }
    console.info("oin done after 30 messages");
    oin.Disconnect();
}
else
    console.warn("Problem listening on default OSC port.");
