This is some seriously sick technology!!
DNA – Direct Note Access is a technology that makes the impossible possible: for the first time in audio recording history you can identify and edit individual notes within polyphonic audio material. The unique access that Melodyne affords to pitch, timing, note lengths and other parameters of melodic notes will now also be afforded to individual notes within chords.
Examples of use:
Tune a guitar after recording
pitch-correct a piano that is out of tune or fix its timing
turn major chords to minor (and vice versa), switch tone scales
mute single notes
remix volume levels, etc.
– all after the performance is already recorded!
