Are you using the OSC Address Space at the bottom, or is that blank? You can check the docs to see how the address is built up, and the correct way to format your addresses.
Notice the extra /s, you want to avoid adding those in your addresses, since they are added for you. So no / at the start of the OSC Address Space, and no / at the start of your OSC Addresses.
Nevermind, got it working. I feel so dumb I didn’t realize this at the beginning. Here’s how I got it working. Thank you for helping me troubleshoot Malcolm!
