Is it possible to make mulitple gain adjustments within V5 to a single audio event?  I want to adjust audio volume within a song to increase and decrease volume as someone is talking on a separate audio track.  I don't want to split the song at each occurance because that creates an envelope handle which either creates a sudden shift in gain, or a fade in or fade out point.  That wouldn't be so bad, except it fades to/from zero gain.  What I'm hoping is that V5 has something similar to the way Studio 8/9 (PinnacleSys) handles volume changes.  Those programs create points on a volume/gain line which can be manipulated to increase/decrease volume gradually, without going to zero gain.  Any help, please?
