Auto-Tune EFX+ is a versatile new vocal production tool, which combines the core features of Auto-Tune with the powerful Auto-EFX multi-effects rack, and Auto-Motion pitch-shifting melodic pattern generator. It includes professional quality Auto-Tune pitch correction with low latency processing for real-time performance on stage or in the studio. Fully adjustable Retune Speed and Humanize parameters let you fine-tune the desired effect for your tracks, from transparent pitch correction to the iconic Auto-Tune Effect. And compatibility with Auto-Key (sold separately) means never having to worry about finding the key of your music before tuning. Auto-Key detects the key and scale and sends that information to Auto-Tune EFX+ with a single click.
