Humanizing your song with Playlist works similarly to Piano roll because you will be working with the snap and zoom settings. Since Playlist allows you to work with audio files, its greatest ability may be that it can adjust the settings of the files. You can, of course, adjust your patterns on the playlist in the same manner, but moving your audio samples or slices is most helpful. As usual, it will come down to your individual workflow. We will be sliding our audio or musical parts forwards or backwards ever so slightly.
