I've become quite familiar with using RealBand. I like being able to add real track and band in the box tracks to accompany myself singing. However, I'm not that great of a singer and I would like to try out some auto-tune software to make my voice sound better.

Is there auto-tune software out there that works well with RealBand? I will sometimes have multiple vocal tracks in a .SEQ file, with one track capturing a particular verse of the song. I would like to be able to apply the auto-tuning to the entire set of vocal tracks, to cover the entire song.

Any suggestions on what software to purchase (or if the feature is already part of RealBand)?
