Sonar Platinum -- maybe I just haven't found it, but in older sonar, there was a Tool button called "Scrub" that allowed one to drag the mouse cursor along the tracks in view in PRV and hear the notes in a tempo dictated by how fast you drag the mouse. It is occasionally handy. Bring it back please (or tell me how to do it ..). (whisper) In cubase when you drag along the velocity lane you get both an immediate correction of the velocity curve plus a very useful scrub function.
