This probably isn't correct in several ways, but it works more than it did, so I figure it's push worthy. Still not working: * Saving mute automation list * Dragged control points are not snapped to model restrictions (boolean, in this case, but general problem) * Line goes funny if you record mute automation (as opposed to drawing it which works)
