This is a great vocal tuner for final polish on a vocal track. I like to use Melodyne manually to do alot of the heavy lifting, but this nice as an insert on vocal tracks in order to catch the little things that are missed...kind of a "final polish" I have not tried to use it low latency, in real time, and don't think I will ever have a need for that, but that is a cool feature for sure! The middle section that has elastic and expressive controls are the key to getting this to sound natural without artifacts, and it does a good job with that. I only subtract a star because it doesn't have a graphical UI, but that is probably subjective on my part
