Pitch correction/tonkorrigering is something that people seem to hate or to love.
Personally, I am rather sceptical about and would rather have a little dirt in the music than it is the data correctly.
Something I have learnt to appreciate with this type of tool is that you can easily find out exactly what is the problem, now if you have a problem.
And if you have a problem so you can fix the tune to the maximum and then use it as a reference to easily find the right pitch when you sing.
It is also an excellent tool for coming up with new vocal melodies or voices.
