It's a good feature in theory, but utterly impractical for live use. You cannot link a .jpg to a Performance (or multiple .jpg's if you need two pages) and it takes considerable button pushing to change the displayed picture. It has a 'slideshow' feature, but there's no way to synchronize the speed of the slideshow to the tempo of the piece you are playing.

Once again, Roland show us how they can take a perfectly brilliant concept, and nerf it to the point of making it useless.

Kudos, Roland!
