Understand Pitch Correction
singers will often use Correct when they are having
trouble.
When pitch correction is only applied in the mains, what
often happens is that if the singer goes really off pitch,
the pitch corrector corrects to the wrong pitch. This
means that the pitch is actually more out than if it hadn't
been corrected in the first place. This is what has given
pitch correction a deservedly bad name for use in live
performance. By monitoring the Guide Output with
Correct, these problems completely disappear.
After using our pitch correction live for a while, some
users who admittedly had pitch problems reported that
their pitch had improved, even without using pitch
correction.
