The Headrush Vocal Harmony FX can be controlled in a variety of different ways to add layered harmonies to any vocal performance. To set up your harmonies to follow your guitar performance, follow the steps below. 


  1. On the Vocal Harmony effect's edit page, the Auto-Src parameter needs to be set to "Guitar", 
  2. Then on the individual voice pages (tap the > on the Vocal Harmony effect page to see them), you need to set the Mode parameter to "Auto", 
  3. Then for the Pitch parameter, you can select between a few different auto-generated harmony types ("Lowest, Lower, Low, Unison, High, Higher, Highest").
