I recently watched a Pro Tools promotion video where the narrater doubled an audio take and used a pitch shifter to create a vocal harmony. It sounded perfect, however it was very fast and I could not catch any technique used to do it. Also, I use Cubase SX3, not Pro Tools 7. Does anybody have any experience doing this (particularily using Cubase)? It seems like such a time saver to do this over recording an actual harmony. Thanks so much!
