Question In the Voice Rack FX app is it possible to recall (via the 4 recall buttons) the position of the slider bar I.e the slider bar remains in the position where you last left it in on a particular preset Answer No, unfortunately the slider automatically returns back to its central position as soon as you have either stored the preset to one of the four radio buttons or changed to a different preset. When you return to a preset (either via the radio buttons or via the list) the slider bar will have returned to the neutral position.
