Our sincerest apologies to our sudden disappearance. We ran into some real life issues that needed to be solved.

And so, without further ado, introducing Celemony.

Celemony is a program/company which has made something truly revolutionary for musicians and dabblers in music editing.
Celemony’s suite called Melodyne has algorithms which allow a user to individually edit each note within a chord. This is the applicable to chorus recordings, piano, essentially all instruments. You can shift an individual note out of the chord, move it out completely, change a chords key, etc. With a suitable library, you could concivably make a recording based solely on previous recordings.
