Using The Pitch Correction Plugin In Logic Pro, Inquiry on how to use the Plugin Options

[redstrype]

I've started to tamper a bit with this plug in, but I find the interface really confusing. I realize each note the vocal hits lights up on the interface piano key, but how do you actually get the vocal to hit the notes you want? I mean how powerful is the plug-in? I read the manual and walked away even more confused, can anyone help explain how to use this plugin in lehman's terms?
Any thoughts would be greatly appreciated!!!


Thank you
