One cool feature of $49 PowerTracks Audio Pro (versions 9 & 10) is that it includes a built-in software vocal processor (TC Helicon) which allows you to easily select & add different types of vocal harmonies to your vocal tracks. I'm wondering if there's a similar dedicated software vocal processor feature included, or available as a 3rd party 'plug-in', for use with 'Cakewalk Sonar 4' as well? Anyone know? Thanks in advance.
