Pitch Correction
Patented On-Key pitch correction automatically modifies voices in real time. Out of tune notes are shifted to the correct pitch without altering the character or quality of the sound.

Voice Shifting
On-Key technology supports a wide range of dramatic alterations to the singer's voice. These include: voice-shifting (which lets children sound like adults, women sound like men and men sound like women), or the popular 'Alien' or 'Techno' effects (which let singers replicate some of today's hottest sounds).

Scoring
On-Key Scoring compares a singer’s timing and pitch accuracy to the lead vocal track, then displays their score on the TV screen. A running score is displayed during song play and an overall score is displayed at the end of the song. This feature provides an objective judge for at-home karaoke contests (or a good coach for improving performances).

Harmony & Duet
Adds one or more simulated voices to the singer's own voice, making the user's karaoke experience as close to a real duet or harmonization as possible.
