You may just b getting the delay from the iPad scrolling action. If that’s what you’re referring to there’s a couple ways you can speed it up a bit. Either drag the faders and stop with your finger before you lift it or flick the faders, then tap a moment to stop the motion. They still will take a bit to settle to a slot but it does speed things up.
You may notice that when you first access faders that you haven’t scrolled too before they seem to update, but after that they have the current settings as well.
