As a teacher i have seen a lot of students and even sound engineers who don't know by which vocal plugin they can get the best result . i have worked with most of these plugins and every plugin has it's own benefits. but among these i found wave tune more suitable. although it is a little bit complicated but in this course every complicated but in this course everything has been explained very easily and everyone can understand them. beside that where as wave tune can handle every scale from west to east i'm sure you will get the most benefit of that. now i will tell you what I've done in this course.
