I sing my own harmonies as well but for the purposes of making them sound really tight, you can make some pretty cool backing tracks. you can allow them to still reflect a human touch by adjusting the level of pitch corection you want. I have not played out in many years and don't anticipate doing so in the future so it's more about just making a solid recording. For me harmonies have always proven to be a challenging endevour. Lets just say no one has ever acused mine of sounding too perfect so I supose that might be i nice change! LOL!
