I've looked at some information on this but I can't seem to control my volume editing in the Hyper window. for one thing, when I try to zoom in on the volume with the zoom tool, it suddenly gets larger but won't return to its former size. Yes, I'm aware of the keyboard arrows but they mostly don't seem to work. Then something new: when I use the pencil tool to draw, it selects a whole section of the volume events and will only edit that selected portion and I can't do a gradual change in volume. It's very frustrating!
