When I open an instance of Impact XT and load a kit instead of there being one channel it loads any number of them, 4 or more? Only the first one, label Impact ST1, ever has any signal, the other three channels are completely superfluous, just taking up space and hogging sliders on my Impulse controller that I would prefer to be able to use for channels that actually have some content. Why does it do this, and is there any way of either stopping it from doing so or otherwise merging them so that my mixer is not full of channels that aren't doing anything?
