If you are interested in an offline tool to correct your singers, based on their actual pitches and with respect to a reference frequency grid, I have developed a Qt4 GUI over Praat that allows exactly this: http://stephane.magnenat.net/data/fys-0.1.tar.gzThis program is currently alpha and limited, but it would allow you to edit the pitch of a singer track. You need a working installation of Praat to make it work. Maybe it is useful to you.
