From my experience your vocal track is what it is, but I have not really played much with pitch correction (which is ironically the thing I need most with my singing ability). I can answer as far as to say that you can record it to a track, mono or stereo, then if you want it thicker you can copy that track to another, play with effects and EQ on the copied track, thus having a backup in case you mess it up with effects (I know from experience to work on a copy and not the original) and tweak your little heart out.

The name "Elastique" implies "stretching out of shape" so I will assume you can do it with that plugin.

Guys?
