OSC Global Remote for TouchDesigner

Driving any operator over OSC

TouchDesigner has Global OP Shortcuts: a name you set once, anywhere in your network, that you can then reach from any script. I wanted to extend that to OSC, so that a control surface (TouchOSC, my phone, a controller) could address any parameter of any operator via a clean address pattern.

The result is OSC_Globalremote on GitHub.

How it works

1. Create a Base or Container and give it a Global OP Shortcut like para1
2. Add custom parameters to it: Gain, Color, whatever you need
3. Drop the OSC_Globalremote Base into the project. It spins up to 10 OSC-In DATs that all share one callback

The address format

/<GlobalOPShortcut>/<Parameter>

So a TouchOSC fader sending to /para1/Gain writes straight into op('para1').par.Gain. No mapping table, no per-project config.

The callback

The onReceiveOSC handler is the whole trick. It parses the address, splits it into shortcut + parameter, and writes the value:

def onReceiveOSC(dat, rowIndex, message, bytes, timeStamp, address, args, peer):
    parts = address.strip('/').split('/')
    if len(parts) < 2: return
    shortcut, param = parts[0], parts[1]
    target = op(shortcut)
    if not target: return
    try:
        target.par[param] = args[0]
    except Exception:
        pass

I run the actual write through a tiny Table → CHOP path so I can re-use the values inside the network without re-parsing.

Feedback back to TouchOSC

Use the OSC_GlobalFeedback Base, but you have to put it inside the target object, so the script knows whose value to publish. That's the one constraint of the system; everything else just works.
