TC Helicon shows off the TC Helicon VoiceLive vocal processor. If you've ever wished you could harmonize with yourself in a live setting, you'll want to see this unit in action. The box doesn't simply appromximate your vocal patterns and tone, this processor has you harmonizing with your own natural-sounding voice. You can pitch up and down, and approximate all your favorite harmonies; Beatles, Eagles, Beach Boys, even that old Cat Stevens "Peace Train" sound.
