I've made this with your instructions 😉. And put it just before OSC Make Message.
This work really well to stop feedback from buttons and incoming OSC Controller Data. It didn't stop the feedback if i moved the "make slider" in the Vuo app.
But i solved that by using a Receive Mouse Drags on Layer and a select output to close the osc input.
And an other question. I'm looking for a node that can route multiple outputs to one input on a first in first out way. The outputs never send data at the same time. So its a bit like "Select input" but where all inputs always send data through to the output. So all inputs are always "open".
