No havent done it wrong written quite a few hog pages for osc with no issues even double checked the text code tonight and its as per manual will check log tomorrow ta
It looks like you are putting spaces in the OSC address between the slashes. Hog is looking for /hog/hardware/iwheelup but you appear to be sending / hog / hardware / iwheelup
When Hog actually processes the message you will be told: i.e. RECV: INTENSITY UP pressed = true
