If you checked that video you would have seen R2 Toggle never lost Focus and I just press Triangle to start synthesize each time using this I would just toggle lay controller down and just use Triangle and 1-2 macro that has been set up!
The only thing they needed to add was a macro that could toggle thru Hold/Toggle/Mixed I really only use Hold/Mixed! I use Hold cause most of them running around I would Hold really quick and hit sprint, and release hold!
