Carolyne,
If you, or anyone else using Windows, would like to try using a pitch correction program, you may want to try the FREE VST called GSnap created by a British company called GVST. The download link for GSNAP can be found
++ HERE ++ Both 32 and 64 bit versions for Windows are available. [
u]Note: Click on the 32 or 64 bit link BELOW the Windows emblem. The big, green download is advertising![/u] The homepage also has links for a screenshot of the VST, online manual and a pdf manual.
There are many "how-to use GSnap" videos available on YouTube.
++ HERE ++ is one of the better videos in my opinion.
