As the slider is moved further towards the right, however, even those notes are influenced, and to an increasing degree, until at 100% all the selected notes are exactly in tune. The macro works in a musically intelligent manner: At lower settings it affects only those notes that are wildly out of tune, leaving untouched those that are already quite close to the intended pitch. If a note wavers slightly in pitch, it cannot be guaranteed that, after 100% correction has been applied to it, it will sound right at the new pitch – especially since the correct pitch of any given note is not a constant but depends upon the musical context. This mean pitch, or “pitch center”, forms the basis for pitch correction. By default, such notes are moved towards, or to, the nearest semitone, but if you check the option “Snap to (the selected scale)”, notes foreign to the scale will be ignored as possible destinations, and, depending upon the position of the slider, notes will move a certain distance towards, or all the way to, the nearest degree of the scale in question.Ī word of caution here: notes often fluctuate slightly in pitch, so their position is based on a mean pitch that Melodyne has to calculate. Here, with the upper slider, you can apply a degree of correction ranging in intensity from 0% (no influence) to 100% (full power) to the pitch center of the notes selected. To open the macro, choose Edit > Quantization Macros > Correct Pitch or click on this button at the top of the Note Editor. If no notes are selected, macro editing will by default affect all notes.
