These Programs can be found on the pedal by using Programs edit mode. Press the Programs button and turn Quick Knob 1, you will see the Granular and Vocal lists, among others: https://cdn.eventideaudio.com/manuals/h90/1.12.5/content/edit-modes/programs.html

The Granular and Vocal lists are Factory lists and cannot be selected as your Playlist to scroll through when using the pedal in Select mode. The idea is that these Programs are starting points and you can pick and choose which ones you like, and then copy them to your User list.
