I want to edit the volume of a given audio track that will let me pull up or down at multiple places. I can fade to cursor but many times I don't want to fade to zero volume. In GarageBand the user creates a node/s and then move them around on the volume envelope as needed. I am not finding a way that allows this type of editing. I want to create a volume curve from any level to any level from point A to point B. A straight line would work but I'm not finding a way to do this. I'm legally blind and the help reference isn't helping.
