Melodyne editor

Melodyne editor, makes possible what had previously been considered impossible: access to individual notes in polyphonic audio material.

Correct wrong notes in a piano recording; change the chords in a guitar accompaniment after the recording is over; refashion a sample lick.
Make notes longer or shorter, louder or softer. Delete notes from chords or add new ones by copying.
With Melodyne editor you can edit your audio material in an intuitive and flexible way.
